How to get week numbers in your Mac menu bar

Menu bar with the week number in the time and date

This post explains how to get the week number in your Mac’s menu bar. Simple enough, right? At some point, as you start planning ahead in basically anything, you’ll run into “week numbers”. Week numbers are weird in that they’re not in your head all the time. But you do need to look them up more than you want. I ran into this and decided: there must be a way to solve this. And there is.

On my Mac the menu bar looked liked this:

And what I wanted was for the week number to be next to the date, in the top right. So first I looked in the Mac’s date settings (System Preferences -> Date & Time), but unfortunately, it doesn’t allow for this. So I started Googling. Quickly I found this tool called Itsycal.

So, I set out to change this.

  1. First, we install Itsycal

    Itsycal is a nice, free, calendar integration in your menu bar, for me it looks like this when I open it, showing a nice outline of my next 3 days:

  2. We configure Itsycal to show the week number

    Copy the top settings, under “Menu Bar” from the screenshot below. The content of the field is E d MMM H:mmm / w

  3. Make sure Itsycal starts on system boot

    To make sure all of this isn’t gone when you reboot your Mac, check the box on the General tab next to “Launch at Login”:Screenshot of Itsycal's general settings

  4. The menu bar should update

    And it should now look something like this, with the Week number nicely showing after the date and time, on the left:

  5. Get rid of the default calendar

    Open System Preferences and go to Date & Time, uncheck “Show date and time in menu bar”. This takes the default date & time out of the menu bar.Date & Time settings in Mac System Preferences

  6. Move the date & time to the right

    You don’t have to do this if you’re fine with the date & time on the left of your icons, but personally I dislike that. Luckily it’s very simple to rearrange your menu bar. Just press & hold cmd on your keyboard and then drag the date & time to the right:Animated gif showing how to drag a menu bar icon to the right

That’s it! Now you have the date in your menu bar, just the way you want it, with the week number.
