Understanding the result
The grid always shows six weeks so the layout stays steady as you move between months. Days from neighbouring months are shown in a muted style. Today is outlined and bold, so it can be identified without relying on colour.
The number at the start of each row is the ISO 8601 week number. It can be switched off if you do not need it.
What does this calendar show?
It is a plain reference calendar for any month from the year 1 to the year 9999. It is useful for checking what weekday a date falls on, for counting weeks, and for printing a clean month page.
It does not manage events or appointments.
How it works
The first day of the month is placed in the column for its weekday, according to the first day of the week you choose (Monday, Sunday or Saturday). The rest of the grid is filled with consecutive days.
Week numbers follow ISO 8601. In a Monday-first calendar each row is exactly one ISO week. If you start the week on another day, the number shown is that of the ISO week containing the Thursday of the row.
Your first-day and week-number choices are remembered in your browser only.
Examples
January 2021 with Monday first
The first row runs from 28 December to 3 January and is labelled week 53, because those days belong to the last week of ISO year 2020. The next row is week 1 of 2021.
February in a leap year
Choose February 2024 to see 29 days. The grid shows 29 in-month days followed by the first days of March.
