Hello everybody, it's the first day of February today (which means that old mister groundhog will be popping his head up soon, a lot of us will be exchanging Valentines Day cards and going out for dinner although not me and I will soon be adding 28 candles to my birthday cake! ) and just looking at the calendar I realized that it's a non leap year this year. I just got finished looking leap years up. I already understood that sometimes February has 28 days and sometimes it has 29, but I still really don't understand why that is. It says that the earth doesn't orbit the sun precisely in 365 days, but if that's the case why do we only have a leap year every four years?
