Calendar Generator

This free calendar generator builds a clean, printable calendar for any year from 1900 to 2100. Choose a full-year layout to see all twelve months on a single page, or switch to a single month for a larger view. Everything updates instantly as you change the options — there is nothing to submit.

You can start each week on Monday (the ISO-8601 and international standard) or on Sunday (common in North America). Turn on ISO week numbers to add a leading “Wk” column, showing the ISO-8601 week for every row — handy for planning, payroll and project scheduling. Enable moon phases to mark the four principal phases — 🌑 new moon, 🌓 first quarter, 🌕 full moon and 🌗 last quarter — on the day each one occurs, and shade weekends to make Saturdays and Sundays stand out. Leap years are handled automatically, and today’s date is highlighted whenever it falls within the calendar.

When you are happy with the result, use Print / Save as PDF to open a clean, ink-friendly printable version in a new window — the on-screen options and site navigation are left out so you get just the calendar.
