Показать описание
It happens once (almost*) every 4 years...Happy Leap Day 2016!!!
*Over a period of 4 centuries, the accumulated error of adding a leap day every 4 years amounts to about 3 extra days. Thus if you cannot divide a year ending in "00" evenly by 400, it's not a leap year.
Most of us don't need to worry about that, as we won't be alive in 2100.
