Can macOS do this without an app?
Partly. The Calendar app can show week numbers: in Calendar, go to “Settings › Advanced”, and enable “Show week numbers”. macOS cannot show the week number in the menu bar.
Week Number shows it in the menu bar, where you can always see it, and it can find the week number of any date.
Can you add custom week numbering options (for example, fiscal weeks, school terms, or work weeks)?
No, the app is intentionally simple.
Why is this free without ads?
I just enjoy making apps. Consider leaving a nice review on the App Store.
Why does it not show week 53?
You are probably expecting ISO week-numbering while having your system set to Gregorian week numbering. You can change it in “System Settings › General › Language & Region”: set “Calendar” to ISO 8601 for ISO week numbers, or to Gregorian for Gregorian week numbers. With Gregorian, the “First Day of Week” setting in the same pane also changes the week numbers.
Why does it show the last days of December as week 1?
That is called ISO week-numbering.
It shows the incorrect week number
You are probably expecting ISO week-numbering while having your system set to Gregorian week numbering, or the inverse. You can change it in “System Settings › General › Language & Region”: set “Calendar” to ISO 8601 for ISO week numbers, or to Gregorian for Gregorian week numbers. With Gregorian, the “First Day of Week” setting in the same pane also changes the week numbers.
How can I change the week number to ISO 8601 format?
Go to “System Settings › General › Language & Region”, and set “Calendar” to ISO 8601.
