How to change the first day of the week in Windows 10's calendar

Windows 10 sets the first day of the week during setup based on your region settings, but it can't adjust the setting automatically if you're visiting another country, or your work schedule starts on a different day.

Fortunately, you can use the Settings app or Control Panel to set the start of the week to any day you want.

In this Windows 10 guide, we walk you through the easy steps to change the first day of the week on your device.

How to set the first day of the week using Settings

In order to change when your week starts on Windows 10, do the following:

  1. Open Settings.
  2. Click on Time & Language.
  3. Click on Date & Time.
  4. Click the Change date and time formats link.

  1. Using the "First day of week" drop-down menu, select the day you want to start the week.

Once you complete these steps, when you open the clock flyout (Windows key + Ctrl + D) it will display the newly configured first day of the week in the calendar. In addition, apps like the built-in Mail and Calendar that use the system configuration will also show your new first day of the week.

How to set the first day of the week using Control Panel

If you feel more comfortable using Control Panel, you can use these steps to set the first day of the week:

  1. Open Control Panel.
  2. Click on Clock, Language, and Region.
  3. Click on Region.

  1. In the "Formats" tab, under "Date and time formats," use the First day of week drop-down menu to set the day you want your week to start.

  1. Click Apply.
  2. Click OK.

After completing these steps, the clock flyout and apps like Mail and Calendar will display the new first day of the week you selected.

  • Did this a while ago.
    Here in Egypt, Saturday is the first day of the week.
  • Saturday? What?!!! Egypt is doomed. Although it seems to have made it since the pyramids, so maybe there is something in this Saturday business.
  • In Egypt, Friday is the weekend and there's Friday prayer.
  • On what planet is Sunday the first day of the week. Geesh :) The working week starts on a Monday, culminating in reaching the "weekend" being the end of the week, leaving Saturday and Sunday as the end of the week. Meaning Monday is the start. Its like MM/DD/YY. Only in America is such crazyness allowed ;)
