How to Calculate Dates Manually
Understanding how to calculate dates is a fundamental skill, whether for planning or historical analysis. The system we use, the Gregorian calendar, has a specific set of rules that govern its structure.
The Basics of the Calendar
A standard year has 365 days. To keep the calendar year synchronized with the astronomical year, a "leap day" is added every four years. This is because the Earth's orbit around the sun takes approximately 365.24 days.
Leap Year Rules
A year is a leap year if it is divisible by 4, except for end-of-century years, which must be divisible by 400. For example, 2000 was a leap year, but 1900 was not. To manually calculate a future date, you must account for the number of days in each month and any leap days you cross.
