Today is the 29th day on February. But why does February exactly have 2 days less than other months which are all 30 days. Legend has it (legend is probably true) that July was named after Julius Ceasar. While August was named after Julius’ successor Emporer Augustus or Augustus Ceasar. Back then August only had 29 days while July had 31.
Well imperial egos are a funny thing and Augustus wanted the month named after him (August) to have just as many days as July (Julius).
So February had to bear the brunt of Emporer’s quirks and had 2 days deducted from it, leaving it with only 28 days. Now August like July has 31 days each.
