Calendars are one of humanity's oldest and most important inventions, dating back over 10,000 years. The earliest calendars were lunar, tracking the roughly 29.5-day cycle of the moon. The ancient Egyptians were among the first to develop a solar calendar with 365 days, divided into 12 months of 30 days each plus 5 extra days. The Romans refined this into the Julian calendar in 45 BCE under Julius Caesar, introducing the leap year concept to account for the fact that the solar year is approximately 365.25 days.
The calendar we use today is the Gregorian calendar, introduced by Pope Gregory XIII in 1582 to correct a cumulative error in the Julian calendar. The Julian calendar's leap year rule (every 4 years) overestimated the solar year by about 11 minutes annually, which had accumulated to 10 days by the 16th century. The Gregorian correction removed 10 days and refined the leap year rule: century years are not leap years unless divisible by 400 (so 1900 was not a leap year but 2000 was). This makes the average Gregorian year 365.2425 days -- extremely close to the actual solar year of 365.2422 days.
Despite the dominance of the Gregorian calendar for international commerce, many cultures maintain their own calendars. The Islamic calendar is purely lunar with 354 or 355 days per year, causing Islamic holidays to shift through the Gregorian calendar. The Hebrew calendar is lunisolar, adding an extra month seven times every 19 years. The Chinese calendar is also lunisolar and determines the date of Chinese New Year. India officially uses the Saka calendar alongside the Gregorian calendar. Understanding these systems is important in our interconnected world.

The generator supports any year from 1 to 9999. Historical dates before the Gregorian calendar adoption (1582) are proleptic -- they extend the Gregorian system backward even though it was not in use yet.
The Sunday-start convention is standard in the United States, Canada, Japan, and several other countries. Many European and ISO-standard calendars start the week on Monday. This generator uses the US convention.
January 31, February 28 (29 in leap years), March 31, April 30, May 31, June 30, July 31, August 31, September 30, October 31, November 30, December 31. The mnemonic "30 days hath September, April, June, and November" helps remember.
