Why Does February Have 28 天??

We can thank the Romans for our chaotic complex calendar system. February has been a neglected month throughout history. Essentially, it got it’s 28 days because the Romans used the lunar cycles to design the months when they should have based their calendar off of the sun. Superstition and politics also played a major part in creating the months. In any case, it’s too late to change it now. Please tell us your thoughts on the calendar system in the comments below.
