Monthly Calendar Generator

This generator builds a clean, printable calendar for any month and year you pick. Choose the month, set whether the week starts on Sunday or Monday, and get a full grid you can print or save. It works for past and future months, counts leap-year days correctly, and lays every date out in neat rows of seven.

How It Works

Formula

grid = blank pads + days 1..N, laid out in rows of 7 from the first weekday

The generator finds the weekday of the first day of the month and the number of days in the month. It adds blank pad cells before the first day so it lands on the right weekday, lists every day, then pads the final row to a full seven days. February uses 29 days in a leap year and 28 otherwise.

Calculation note: values are processed in the order shown above, using the current input units.

Worked Examples

Build a December 2025 calendar

MonthDecember
Year2025
Week StartSunday
Result31 days, starting on a Monday, laid out across 5 weekly rows

December 2025 has 31 days and the first falls on a Monday. With a Sunday start, the first row begins with one blank cell, then December 1 sits in the Monday column.

Build a February 2024 calendar

MonthFebruary
Year2024
Week StartSunday
Result29 days, starting on a Thursday

2024 is a leap year, so February shows 29 days. February 1, 2024 falls on a Thursday, so the first three days sit at the end of the opening row.

A leap year happens every 4 years, except for century years that are not divisible by 400. So 2000 was a leap year but 1900 was not.

Common mistakes

  • Forgetting that February has 29 days in a leap year. The generator handles this for you based on the year you pick.
  • Assuming every month starts on the same weekday. The starting weekday shifts each month, which is why the blank cells move.
  • Mixing up Sunday-start and Monday-start layouts. Set the week start to match your region so the columns line up the way you expect.
