Frequently Asked Questions
What is the Gregorian calendar?
The Gregorian calendar is the most widely used civil calendar in the world today. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. It corrects for the Julian calendar's slight inaccuracy in calculating the solar year by refining the rules for leap years.
What is a leap year?
A leap year occurs every 4 years to keep the calendar year synchronized with the astronomical year. A leap year has 366 days instead of the usual 365, with the extra day being February 29th. The rule is that a year is a leap year if it is divisible by 4, except for end-of-century years, which must be divisible by 400.
Why does the calendar only go from 1900 to 2100?
This range was chosen to cover the most common use cases for a modern calendar tool while ensuring fast performance. This 201-year span is sufficient for nearly all contemporary date-checking and planning needs, from historical lookups in the 20th century to planning for the future.
