Printable Calendar Maker (PDF)

Make a clean monthly calendar to print or share as a PDF. Choose the year and a single month or all twelve, start weeks on Sunday or Monday, and pick US Letter or A4 in landscape or portrait. US federal holidays (with observed days) or South Korean public holidays can be marked, and you can add your own birthdays and events. The PDF is built on your device; nothing is uploaded.

How to use this tool

1. Choose the year and either one month or all 12 months.
2. Pick the first day of the week, the paper size and the orientation.
3. Choose which holidays to show and whether to add note lines under each month.
4. Optionally list your events, then press Calculate and download the PDF.

Formula

Leading blank days = weekday of the 1st (counted from the chosen first day) · rows = ⌈(blank days + days in month) ÷ 7⌉

Each month gets one page with 4 to 6 week rows. US holidays follow 5 U.S.C. 6103: fixed-date holidays falling on a Saturday are observed on the Friday before, on a Sunday the Monday after; Monday holidays use their rule (for example the fourth Thursday of November for Thanksgiving; Veterans Day was the fourth Monday of October from 1971 to 1977). Korean holidays include lunar-calendar dates and substitute holidays under the rules in force from 2026, when Labor Day and Constitution Day became public holidays.

Example

For 2026 with US holidays, the calendar marks 11 federal holidays plus Friday 3 July as the observed Independence Day, because 4 July 2026 is a Saturday. Choosing South Korea instead marks 22 dates, including the substitute holidays on 2 March, 25 May, 17 August and 5 October.
