“This February cannot come in your lifetime again. Because this year February has 4 Sundays, 4 Mondays, 4 Tuesdays, 4 Wednesdays, 4 Thursdays, 4 Fridays and 4 Saturdays. This happens once every 823 years. This is called money bags.” This message that we received last week through a WhatsApp forward caught our attention – and got us a little ticklish. First, let’s get the facts right: 2016 is a leap year, and February has 29 days, which means that one day will repeat 5 times. In this case, it’s Monday – there are 5 Mondays in February 2016 (and not four as claimed in the ‘viral’ message). And even if this wasn’t a leap year (it is), February would still have 28 days in it, meaning exactly 4 weeks. Which means that, leap year or no leap year, there is no way any February won’t have 4 Sundays, 4 Mondays, 4 Tuesdays… you get the drift, right?

The month of January had five weekends – it had 5 Fridays, 5 Saturdays and 5 Sundays.

When a month has 28 days, this can't happen. When it has 29 days (February of every leap year) it happens only when the first day of the month is a Saturday. When a month has 30 days, then if the first day of the month was a Saturday, you would also get 5 Sundays. To get 5 Saturdays and only 4 Sundays, then, means the first day of a 30-day month has to be a Friday. For a 31-day month, you need the first day of the month to be a Thursday, so that days 3, 10, 17, 24 and 31 are Saturdays and days 4, 11, 18 and 25 are Sundays. A rough calculation would suggest that the probability of getting the Saturday on the first day of a 29-day month is 1 in 7, that of getting it on the second day of a 30-day month is 1 in 7 and getting it on the third day of a 31-day month is 1 in 7. So any given month (except February on non-leap years) has a chance of about 1 in 7. 28-day months happen 97 out of every 4800 months in the current Gregorian calendar. So for the other 4703 months out of 400 years, there's a 1 in 7 chance. According to my calculations, it's a 14.00% chance of it happening in the long run, or about once every 7 months on average.

Why does February have only 28 days? Blame the Romans. Well, we can blame them for at least part of the reason. February got shortchanged – in comparison with its 30- and 31-day counterparts – thanks to Rome's agricultural season. And it stayed that way to, well, keep time running like clockwork. The original Roman lunar calendar spanned 10 months. January and February were later tacked on at the end, says Cynthia White, a University of Arizona classics professor and director of the Basic Latin Program. "In winter, the agricultural cycle was dormant and so not counted," White said, adding that research indicates that Numa Pompilius, who served as the second king of Rome around 700 BC, made the additions. The calendar would go through a number of additional adjustments, especially under Julius Caesar and Pope Gregory XIII. To shed more light on February's 28 days, White joined John Bauschatz, UA associate professor of classics, in answering a few questions about time keeping and the history of February. "Though February may be small, it's also a very important month," said Bauschatz, who admits his birthday is in February, but won't reveal the day. February is also when we recognize American Heart Month, American History Month and Black History Month. "It also contains the occasional leap day, one of the quirkiest holdovers from the Julian calendar reforms. And best of all, its shortness helps us all get through the winter more quickly." Q: Let's begin with some contextual ...

February will have 30 days in the year 7008. The reason for this is basically due to the same reasons we have leap years every four years (mostly). In the year 1752 the month of September was reduced by twevle days due to the fact that century years not devided by 400 still had leap year status i.e. 100,200,300 et. By 1752 there were 13 such years. because of this, these years were deducted from the month of September. However ONLY 12 day were removed. -- The reason for this is that, in the calander sense, there were 13 years, however in a mathematical sense there were only 12 1/4 days. I assume since 1/4 is less than half the 13th day was not also deducted. -- However, that quarter day will not go away and, in fact, will eventually become a 1/2,3/4 and finally a full day. Since it took until 1752 for a 1/4 day to be accumulated, it will take another 1752 years times 4 for a full day to be accumulated. That year will be 7008 a leap year, and also the year that February will have 30 days. One day for the normal accumulation of annual time for four years and one day for the accumulation mellennial time. -- Conceivably, since fractional seconds also accumulate, somewhere in the very distant future there could be a February 31st--if civilization is still around to count the fractional seconds. -- Robert Hayes Halfpenny

Advertisement Some historians believe that February once, had 29 days, but Augustus Caesar stole a day and added it to August since the month was named after him. While the story seems plausible, it has largely been discredited as a myth. The month ‘February’ was a Roman afterthought, who used the Calendar of Romulus until the 8th century, which was a 10-month calendar starting off in March and ending in December. The months of January and February didn’t even exist. Martius: 31 days Aprilius: 30 days Maius: 31 days Junius: 30 days Quintilis: 31 days Sextilis: 30 days September: 30 days October: 31 days November: 30 days December: 30 days The problem was that the year had only 304 days. The Romans didn’t care for January and February since they were mainly planters and harvesters. Thus, they felt no need to create a timetable for these winter months. Soon afterward, came King Numa Pompilius in 713 BCE, who pointed out the problem with neglecting one-sixth of the year. So he arranged the year in 12 lunar cycles and introduced January and February, which amounted to 355 days in total. The months were added at the end of the calendar, making February the last month of the year. But no Roman story is complete without some superstition and mysticism! The Romans considered even numbers to be unlucky, so Numa tried to make every month odd. But to get a total of 355, one month had to be even. Thus, the “unlucky and ungainly” month of February got the short stick, which made the ca...

24 Was there a 0 year? Why is February 29th only every 4 years? Why Are Leap Years Necessary?
