Monday first, weekend together
US calendars traditionally start the week on Sunday, which splits the weekend across the two ends of each row. A Monday-first calendar keeps Saturday and Sunday side by side at the right, so the five working days line up on the left. That is the layout most people want for a work schedule, a shift rota or a gym plan.
What the week numbers mean
The numbers at the left (W1, W2 and so on) are ISO 8601 week numbers, the system used by most European businesses, many project tools and spreadsheet functions such as ISOWEEKNUM. Under ISO 8601:
- weeks start on Monday;
- week 1 is the week that contains the year's first Thursday, which is the same as the week containing January 4;
- a year has 52 weeks, or 53 when it starts on a Thursday (or on a Wednesday in a leap year).
So the first days of January can belong to the last week of the year before. January 1, 2027 is a Friday, and it falls in week 53 of 2026. The calendar prints the week number of each row's first date in the month, which is what you need to match a "week 14" deadline to real days.
Worked example: March 2027 with week numbers
Set Month to March, Year to 2027, Week starts on to Monday and turn on Week numbers. March 1, 2027 is a Monday, so the month opens with a full first row and no empty boxes. The week number column beside that row prints W9, because the first ISO week of 2027 is the one that holds Thursday, January 7.
The month runs to Wednesday, March 31, in week 13, so the page shows weeks 9 to 13 in five rows. Saturday and Sunday sit together at the right of each row, which is where most people block out the weekend.
The settings
This page opens with Monday start and week numbers on. You can still change anything:
- Month, Year and Pages pick the month (1900 to 2100) and whether to print one page or twelve.
- Holidays prints US federal holidays and observances, federal holidays only, or none. Most people using ISO weeks outside the US choose None and write in their own.
- Orientation, Notes lines and Dates (filled in or blank) work as on the printable monthly calendar.
For a year at a glance with Monday-first months, open the yearly calendar and set Week starts on to Monday.
