How your printable is made

Calendar dates & week numbers

Dates use the Gregorian calendar in UTC. A leap year is divisible by 4, except century years not divisible by 400. ISO weeks start on Monday; week 1 is the week containing January 4. Sunday-start rows are labelled with the ISO week of the Monday in that row.

Holiday scope

Country calendars use nationwide public holidays from vendored Nager.Date snapshots. Regional holidays and school breaks are excluded. US calendars show federal holidays and weekend observed dates using OPM rules: a Saturday holiday is observed on Friday and a Sunday holiday on Monday. Inauguration Day is not a nationwide federal holiday and is excluded.

Paper & precision

Letter is 215.9 × 279.4 mm, A4 is 210 × 297 mm, Legal is 215.9 × 355.6 mm, and A5 is 148 × 210 mm. Graph sheets center complete grid cells inside margins of at least 12.7 mm. PDFs preserve exact dimensions when printed at 100%.

Preview & PDF

Both are produced from one set of drawing operations. Preview images are scaled to fit your screen. Download the PDF to print; do not print a screenshot. The PDF embeds its text font.

Personal certificates

Gift and achievement templates are for informal use. Text wraps and scales within the printable bounds. They are not official records, qualifications, or legal certificates.
