The first 4 Wednesdays in February and March this year have the same date number.... Is it possible to have 5 Wednesdays like this?  Only 3 Wednesdays? Does this happen in any other pairs of months, either adjacent or non-adjacent months in the same year? If so, why

Yes, this actually happens for March and November as well. In this case, there are 5 Wednesdays each in March and November of 2006. Both sets of Wednesdays have the same date number.\n\nIt happens because the number of days between March 1 and November 1 is a multiple of 7. In this case 245 days, which is exactly 35 weeks. Hence, it happens :)

Just go through it like any other day... No big deal. Chill out. You probably feel bad not because you need your friends that much but because you haven't found that special someone. But I see no reason why this has to be the accent on Valentine's day. Until you find your other half, it's just a day in February. Go chat online, you'll find a lot of people like you and perhaps you could even meet The One. Hugs!!

All of the above. No doubt about it. In a standard day the order is 4,2,3,1. Some days bear cycling through - e.g. yesterday was 4,2,4,2,3,2,1,1,4.

February used to have 29 days and 30 - in leap years - before Augustus Caesar's ego messed it up.\n\nThe Roman year began in March and February was the 12th month. After June came Quintus (the 5th month) of 31 days and Sextus (the 6th month) of 30 days. Followed by September (the 7th month), Julius Caesar decided to name Quintus after himself and we now know of it as July. \n\nThen when Augustus Caesar became Emperor he decided he would change the name of Sextus and name it after himself. As that would mean his month has one day less than July and imply he was a lesser emperor than Julius Caesar had been, he decreed that August should have 31 days not 30 and he therefore lopped a day off February,\n\nSo your proposal merely seeks to restore us to the calendar as it was prior to Augustus Caesar's interference,\n\nThe Babylonians with their sexagesimal (base-60) counting system which gave the world 360 degrees in a circle, also had 360 days in a year and 12 months of 30 days, Unlike the French solution, they added their extra days in the form of a 13th month, once every 6 years.\n\nThe French Republican calendar was a thorough overhaul of the system, introduced in the context of the world's first metric system, and involved not only 12 30-day months but 3 10-day weeks in a month, 10 hours in a day. 100 minutes in an hour and 100 seconds in a  minute. The months had new names, the year began in the autumn and Year 1 was the date of the Declaration of the French Republic\n\nClocks were built to tell the time by these rules but they did not catch on. Napoleon officially abandoned the calendar on 1st January 1806, after little more than 12 years of use. It briefly resurfaced and re-emerged again at the time of the Paris Commune in 1871, but it has not exactly attracted swarms of advocates before or since.\n\nMy conclusion is that people are set in their ways, see no great pressing need for change and that as there is no exact, mathematically neat solution to the fact that a year is not an exact number of days (nor is a lunar month either) whatever system we use will be a bit inelegant, and acknowledging that, most people would say "let's stick with what we have got. It's easier. Then we don't have to learn anything new."\n\nInertia, apathy and habit will all argue against change, I fear! However logical the change may be.

TWO WAYS TO REMEMBER HOW MANY DAYS IN A MONTH\n\nA RHYME:\n30 days has September, APRIL, June and November.\nAll the rest have 31 except February alone which has 28 or 29 on a leap year.\n\nA STRANGE COINCIDENCE\nClench your fists and put your knuckles together side my side. The first knuckle on the left of your left hand is January, then moving to the right there is a dip, this is February, then there is the next knuckle, March, etc. until you get to December on the middle of your right hand. All the knuckles are 31 days and all the dips are 30 (except February, which is an exception, as above)

So simple.... The letter "E" ...\n\nThe day means...sunday monday, tuesday, wednesday, thursday, and so on....\n\nTuesday have one "E" and Wednesday have two "E" so there are 3 "E" in day... \n\nAnother way to justify this is by listing morning, afternoon, evening and night. if you count the "E" there are 3 "E".\nSo that explains it...Am i right guys?...

Okay, this is not going to be pretty, but it works, but only for years from A.D. 1582 and later.\n\nFirst, let M equal the number corresponding to the chosen month according to the following list\n\nJan=11\nFeb=12\nMar=1\nApr=2\nMay=3\nJune=4\nJuly=5\nAug=6\nSep=7\nOct=8\nNov=9\nDec=10\n\nNext, let N equal the day of the month for which you are inquiring.  So if you want to look for August 15, M would be 6 and N would be 15 (M=6, N=15).\n\nNow, take the last two digits from the year you are searching for, call that number Y.  For 1947, Y=47.\n\nThe leftover digits of the year make a new number, call it C.  For 1947, after removing 47 we see that C=19.\n\nFinally, if the year is a leap year, let L=1, otherwise, let L=0.\n\nNow we're ready to get down to business.  The following formula makes use of the greatest integer function (ipart) which essentially means that if you get some number with a decimal, chop off the decimal.  3698.2461 becomes 3698.  OK?  Good.\n\nNow we must calculate the following formula:\nN + ipart(2.6M - 0.2) + Y + ipart(Y/4) + ipart(C/4) - 2C - (1 + L)*ipart(M/11)\n\nAfter calculating this number, divide it by seven and look at the remainder.  The remainder corresponds to the day of the week as follows:\n\n0=Sunday\n1=Monday\n2=Tuesday\n3=Wednesday\n4=Thursday\n5=Friday\n6=Saturday\n\nLet's test this with your August 15, 1947.\n\nSo, M=6, N=15, Y=47, C=19, and since 1947 was not a leap year, L=0.\n\nPlugging these values into the formula we get:\n15 + ipart(2.6*6 - 0.2) + 47 + ipart(47/4) + ipart(19/4) - 2*19 - (1 + 0)*ipart(6/11)\n\n=15 + ipart(15.4) + 47 + ipart(11.75) + ipart(4.75) - 38 - 1*ipart(.5454545454)\n\n=15 + 15 + 47 + 11 + 4 - 38 - 0\n\n=54\n\nDividing this by 7, we get a remainder of 5.\n\nThis says that August 15, 1947, was a Friday.

Yes there is a formula for working it out. They do not actually remember every date and day. I have it in one of my books, I'll find it and add it here later.\n\nHere's a link to site that does the calculations.\nhttp://216.109.124.98/search/cache?p=how+do+i+work+out+what+a+day+of+the+week+was&prssweb=Search&ei=UTF-8&meta=vc%3D&fl=0&fr=ush-ans&u=www.nightmare-relm.co.uk/guest/birth.php&w=work+day+week&d=VgBk9JIFNyTS&icp=1&.intl=uk\n\nI'm still checking my books for the formula\n\nRight I'm back. I've found the answer. I\nYou have to memorise a lot of codes for different days and  months. It's too complicated to write here and I'm not sure that so-called "mindreaders" would be too happy if I gave away the secret.\n\nYou can by a CD with instructions on how to do it.\nhttp://www.world-of-magic.co.uk/magic.asp?id=16568\n\nSorry I couldn't be more help

Our version is a bit different.\n\n30 days has September, April, June, and November.\nAll the rest have 31\nExcept February \nWhich has 28 Days clear \nAnd 29 each Leap Year.\n\nMondays child is fair of face,\nTuesdays child is full of grace,\nWednesdays child is full of woe,\nThursdays child has far to go,\nFridays child is loving and giving,\nSaturdays child works hard for his living,\nAnd the child that is born on the Sabbath day\nIs bonny and blithe, and good and gay.

Signed with the following comment...\nYa know there's 6/6/2006 and 6/6/1906 and 6/6/1806 and there will be 6/6/3006 and 6/6/4006.  Why is this so special?

i see them too. it started with 222 and 333 to a lesser extent.  I went through a whole semester in a classroom  numbered MB0222.  Today i saw it twice 2:22 PM on my wristwatch, then 3:33 PM on my computer clock.  yesterday it 4:44 and 5:55.  i used to wake up exactly at 2:22 AM and sometimes 3:33 AM.  Before the gas prices skyrocketed. I used to pass gas stations with $2.22 advertised. It started for me around late spring. I have goose bumps writing this. I feel so f'd up sometimes. My girlfriend tries to console me saying they are irrational coincidences. In my rational mind i know this to be true, but there is something pulling at me. I don't know what it is. I'm sorry you share this affliction. I know it's concerning. For me, now, it's a matter of routine and i dismiss the occurrences as annoyances of my mind. good luck to you. -r

I've known a few people who were born on February 29th and most did things like the other people described.  But some enjoy the experience by celebrating their 5th birthday when people born the next day would be celebrating their 20th birthday.  An Aunt in her 80's jokes about being married to a 20 year old when in actuality her husband is a few month older than her but born on February 29.  Whatever you do, have fun!!!  My suggestion is to throw yourself a huge party every four years to make up for the other three years when there wasn't a February 29.

I'm not sure what he means by his explanation, but he's not totally off to think there would at least be a possibility of the longest 'day' not being adjacent to the shortest 'night'.\n\nAs measured from the Sun's local zenith to the next local zenith, solar days are not the same length of time (24 hours is just the average amount of time to get from noon to noon).  It takes longer to get from local noon to the next local noon at the solstices when the Earth is tilted directly toward or directly away from the Sun.  The shortest solar days (noon to noon) should be at the equinoxes.  (In other words, if there are more total seconds in the solar day at the solstice, then having the most daylight seconds doesn't necessarily mean having the shortest night time seconds).\n\nAdditionally, the Earth's orbit is slightly elliptical.  At perihelion (closest point to the Sun), the Earth is traveling faster and sweeping out a bigger angle per second.  That means the Earth has to rotate further to get back to noon the next day.  Solar days near perihelion are longer while solar days near apohelion (furthest from Sun) are shorter.  This is where your dad's argument starts to break down.  The Earth is at apohelion around the first week of July and at perihelion the first week of January.  In other words, there are more seconds in a solar day in the winter than there are in the summer.  The tilt of the Earth is more significant, so there are still more seconds in a solar day near the summer solstice than either equinox, even if the longest solar day (noon to noon) isn't in the summer.\n\nThe biggest reason his argument breaks down is sheer magnitude.  The variation in the length of a solar day is in seconds/day while the difference in the amount of daylight/darkness can be minutes/day (the amount of variation depends on a person's latitude)\n\nFor 2006, the longest daytime period will be on Jun 21, with the shortest nightime period being Jun 20 or 21 (the Naval Observatory's charts only list hours and minutes).

Nope it has to be 2 full moons.  Not 2 new moons.  There's only been one full moon this month.  there will be, however, two new moons.  one was on the 1st and the other will be the 31st....  the full moon happened on December 15th.\n\nA "Blue Moon" is the name given to the second full moon in a calendar month. Because there are roughly 29.5 days between full moons, it is unusual for two full moons to "fit" into a 30 or 31 day month (and impossible to fit into a 28 or 29 day month, so February can never have a Blue Moon). The saying "Once in a Blue Moon" means a rare occurrence, and predates the current astronomical use of the term, which is quite recent. In fact, Blue Moons are not all that rare, on average there will be one Blue Moon every 2.5 years. After 1999, the next Blue Moons will be in November 2001; July 2004; and June 2007. The last one before 1999 was in July 1996. \nThe term Blue Moon is believed to have originated in 1883 after the eruption of Krakatoa. The volcano put so much dust in the atmosphere that the Moon actually looked blue in color. This was so unusual that the term "once in a Blue Moon" was coined. However, Blue Moon was also used in much the same way we use the term "Harvest Moon". There were twelve names for full moons, one for each month, and the name Blue Moon was used in years which had 13 full moons. It referred to the third full moon of the four occuring between an equinox and solstice in that year. A misinterpretation of this led to a Sky and Telescope Magazine "Star Quiz" in July 1943 followed by an article in March 1946 which stated that the second full moon in any calendar month was called a Blue Moon (attributed to the 1937 Maine Farmers' Almanac), and this definition has now become part of the language. \n\nIn January and March of 1999, we had a situation which only takes place about four times a century: two Blue Moons occurring in the same year. The last time this happened was in January and April of 1961 and it will not happen again until January and March of 2018. A double Blue Moon most commonly occurs in January/March but is also possible in January/April or January/May and only when there is no full moon at all in February. It is also possible to have a Blue Moon in December of one year and March of the next year, again, there is no full moon in the intervening February. \n\nThat might have been way more info than you wanted, but now you know... and knowing is half the battle.

I don't know for certain, but it's probably the changing season from winter to spring - as weather fronts alternate between warm and cold with greater frequency, there is simply more opportunity for the wind to claim any given day in March.  As the season turns more consistently warmer, the winds die down overall.

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by 4, except for century years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1996 was a leap year whereas 1999 was not, and 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not.\n\nThe reasoning behind this rule is as follows:\n\nThe Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox. \nThe vernal equinox year is currently about 365.242375 days long. \nThe Gregorian leap year rule gives an average year length of 365.2425 days. \nThis difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years' time the length of the vernal equinox year will have changed by an amount we can't accurately predict (see below). So the Gregorian leap year rule does a good enough job.

my claim is that the number is infinite.  here is the reason, it depends on who you classify as a mathematician and what date you want to start at.  Also i claim that you can move forward in time, which i will claim is infinite, and find more mathematicians bore in march.
