Tinta Si Isteri Mekanik: Leap Year

29 February 2012

Leap Year

Why is there a leap year?

Since it takes 365 and 1/4 days for the earth to revolve around the sun, 

one day needs to be added every four years (Feb. 29th) 

so that the calendar and seasons don't get out of whack. 

(Otherwise, after about 730 years, 
summer would be in what are now the winter months, 
and winter would be in what are now the summer months.) 

And because there is really 365 days, 6h, 9mins 
so that 6hrs 9mins turn into a whole day.
