Navigate, then select a day
Choose a month and year or use the previous/next controls. Click a numbered day in the active month to see its date details. Faded days belong to an adjacent month and are spacing hints; move to that month to select them.
Check leap years
February 2024 has 29 days; February 2025 has 28. Gregorian years divisible by 4 are usually leap years, except century years not divisible by 400. Thus 2000 was a leap year and 2100 is not. This distinction matters when planning an anniversary several decades ahead.
What a highlighted day means
Today follows the device’s date. Weekend styling marks Saturday and Sunday, which may differ from your work schedule. The page is a Gregorian calendar, not an official holiday, school-term or lunar-calendar source. Verify local public holidays separately before arranging travel or leave.
