By default, the first day of the week is set to Sunday. You can configure this in your preferences on the TomTom Sports website .
Changing the first day of the week re-calculates all your Goals, Trends and Progress graph calculations. When you sync your compatible Sports device (see below), the new setting is applied to your TomTom Sports device.
- TomTom Sports website and TomTom Sports App
- All TomTom Activity Trackers
- TomTom Runner 3, TomTom Spark 3, TomTom Adventurer*
- TomTom Runner 2, TomTom Spark*
* For now you can only sync the setting for the first day of the week to these devices using the TomTom Sports Connect desktop app.
