Did You Know?
The Gregorian calendar we use today was introduced in 1582 to correct drift in the Julian calendar. Because some countries adopted it later than others, historical date calculations can differ by up to 13 days depending on which calendar was in use at the time. For modern dates, the calculation is always straightforward: one day is exactly 86,400 seconds.
