Calendar Maker

Choose a year from 1 to 9999, a month, and Monday or Sunday as the start of the week. Select Full year for all twelve months. Generate the preview explicitly; changing a setting removes the old preview and disables printing until you generate again.

The calendar uses the proleptic Gregorian calendar, including years before its historical introduction. Leap years are divisible by four, except century years unless divisible by 400. Thus February 1900 has 28 days and February 2000 has 29. Local calendar reforms and holidays are not included.

Every month has six rows of seven days. Empty cells lie outside the selected month. Note lines add three writing lines to each day. Print uses the same generated calendar, with one month per page for A4 or Letter in portrait orientation; paper, margins and scaling remain adjustable in the browser’s print dialog. If a pop-up is blocked, allow it and select Print again.

Valid settings are retained between visits. The preview is generated only when requested, including after a reload. Month and weekday names follow the app language; calendar dates do not depend on your time zone or browser locale.
