Did You Know? Your Calendar's Quirks Are Thanks to Roman Rivalry!

Posted on Jun 1, 2026
tl;dr: The reason July and August both have 31 days, making February so short, is because Roman Emperors Julius Caesar and Augustus each wanted their namesake months to be equally long and prestigious, effectively 'stealing' a day from February.

Okay, so you know how some months have 30 days, some have 31, and then there’s poor February, just hanging out with 28 or 29? Well, it turns out that the reason July and August both get to be long, 31-day months, while February got the short end of the stick, is a pretty fun bit of ancient Roman history and a dash of emperor ego!

Back in the day, Julius Caesar was a big deal, and he reformed the Roman calendar, giving us something much closer to what we use today. He even got a month named after him: Quintilis became July, and he made sure it had a respectable 31 days. Fast forward a bit, and his adopted son, Augustus, became the next incredibly powerful emperor. Naturally, Augustus wanted his own month too! So, the month of Sextilis was renamed August. But here’s the kicker: Augustus wasn’t going to let his month be any less grand than Julius’s. He insisted that August also have 31 days.

To make this work without messing up the entire year’s length too much, they essentially ‘borrowed’ a day from February. So, next time you’re wondering why February feels a bit stingy with its days, you can blame a couple of Roman emperors who just really wanted their legacy months to be equally impressive! It’s a neat little peek into how even something as fundamental as our calendar has these surprisingly human, historical quirks woven right into its fabric. Pretty wild, right?
