Why Does February Only Have 28 Days?


[MUSIC] Although February 2015 might fit perfectly
on the page, every year it’s the runt of the monthly litter. This deficit of days,
this calendar craziness, this oddity of the annum, like so much of modern culture, is
the Romans’ fault. Here’s the crazy story of why February has 28 days… except when
it doesn’t. [MUSIC] Romulus, the maybe-mythical, maybe-real founder
and first king of Rome, had a problem. With an increasing number of festivals, feasts,
military ceremonies, and religious celebrations to keep track of, Romans needed a calendar
to organize all of them. Ancient astronomers already had accurate calculations
for the time between two solar equinoxes or solstices, but nature had given people a nice,
easy pie chart in the sky to track the passage of time, so early Rome, like many other cultures,
worked off a lunar calendar. The calendar of the Romulan republic had ten
months of either 30 or 31 days, beginning in March and ending in December, and we can
still see traces of that calendar today. Problem was, that year was a few days short
of four seasons. Romans were too busy not dying during winter to count those 61 and
a quarter extra days… they’d just start the next year on the new moon before the spring
equinox. It’s actually not a bad system, as long
as you don’t have to figure out what day it is between December and March. So the second king of Rome, Numa Pompilius,
tried something else. Even numbers were bad luck in Ancient Rome,
so Numa started by removing a day from all the even-numbered months. And being loony for Luna, Numa wanted his
calendar to cover 12 cycles of the moon, but that would have been an even number, so he
rounded his year up to 355. Numa split the remaining days into two months and tacked
them on to the end of the year. And that’s how February got 28 days. Yes,
it’s an even number, but since the month was dedicated to spiritual purification, Romans
let that one slide. But, as powerful as Rome may have been, they
couldn’t change the rules of the universe, and neither of these calendars add up anywhere
close to the time it takes us to orbit the sun. After a few years, the seasons are out
of whack with the months, dogs and cats, living together, mass hysteria!! Did we already use that joke? This is where it gets even weirder. See, February was actually split in two parts.
The first 23 days and… the rest. Every year, Numa’s superstitious calendar
would be out of line with the seasons by a little more than 10 days. So every other year,
the last few days of February were ignored and a 27-day leap month was added after February
23rd or 24th. This way every four years would average out
to 366 and a quarter days… which is still too many days, but hey, we’re getting there. Confused? You should be. Numa! This system could have worked, every 19 years,
lunar and solar calendars tend to line up, so add enough leap months to keep the seasons
in order and eventually everything will reset itself. Except these leap months weren’t always
added according to plan. Politicians would ask for leap months to extend their terms,
or “forget” them to get their opponents out of office. And if Rome was at war, sometimes the leap
month would be forgotten for years, and by the time Julius Caesar came to power, things
had gotten pretty confusing. Caesar had spent a lot of time in Egypt, where
365-day calendars were all the rage, so in 46 BC, he flushed Rome’s lunar calendar
down the aqueduct and installed a solar calendar. January and February had already been moved
to the beginning of the year, and Caesar added 10 days to different months to get a total
of 365. And since a tropical year is a tad longer
than 365 days, Julius added a leap day every four years, except they inserted it after
February 23, right in the middle of the month. Apparently February is the trash heap of the
calendar, just do whatever feels good. For all their work to reform the calendar
and other stuff they did, the 7th and 8th months of the year were renamed for Julius
and his successor Augustus Caesar, despite the fact that Pope Gregory would have to adjust
it again in 1500 years. But that’s a
story for a different day. Or month. I don’t even know anymore. Stay curious.

  1. To me it all just runs together 🙂 Half of the time I do not know what the date is. I only follow bill dates of when to pay things. I live more by the universe where there is no date or time.

  2. They could have learned a lot from the ancient Hebrews. Once they couldn't use Jerusalem to view the new moon, they created a calendar that added an extra month seven times each nineteen years. It was called Adar II, and kept the holidays "in their season" as required by the Bible.

    Muslims don't do this, so their holidays float through the year. During Ramadan, they may have to fast anywhere from short winter days to loong summer days.

  3. Please give translation or subtitle to every posts, it may help more to those who don't get ur words well. Like me :v . Thanks. Sorry my words.

  4. I got #NOTHING….except what he said in last…."February is a junk"
    Now that made be #SAD bcz I was born in February month.(back in 1998)….👶👼😐😕😕😋

  5. A year should be divided into 13 months of 28 days each. Exactly 4 weeks per month. And then 2 days for New Year's, belonging to no month.
    😞<What would you call the 13th month?
    "Stevember"

  6. February has 28 days to piss off every boss of the company because they have to pay their employees the full salary for 2 days less of work 😂

  7. Cz folk were tired of Winter and wanted Spring to happen so they chopped off three days at the end of the yuckiest month.

  8. Don't know why it's has 28 days, but I can guess that's why we made it Black History Month, the shortest, coldest, crappuest month of the year.

  9. there used to be 30 days in febuary if your in sweden and finland in the 18th century (im not gonna explain it search it up im not joking)

  10. man i loved that part :
    " see february was actually split into two parts. the first 23 days and…." (28-23 equals?…..) " the rest ."

  11. At first this video was confusing, but after watching it a few times it made perfect sense. Great video!

  12. Who else noticed in J F M A M J J A SO N D it has a secret message. JASON. Actually that's my cousins name

  13. I wanna curse the fact that it is in every four years, how am I suppose to use the benefit of free birthday passes, wait for four years? Exactly.

  14. Ten months is actually a pretty sound system. You start on what's now December 22, the day after midwinter, and have 5 months of 36 days and 5 months of 37 days – And the day after Midsummer will be on the first day of the sixth month. All the extra days you may eventually need, you can add to the 10 month to get in line with the start of the new year. The Romans were nearly there.

  15. fun fact : There is no physical evidence to say that today is Sunday, we all just have to trust that someone has kept count since the first one ever.
