Start Your Week on Monday
Need your calendar to start on Monday (or any other day)? We've got you covered! Click your avatar in the upper right corner, and select the Preferences option:
From there, under
First day of the week , use the drop-down arrow to select
Monday instead of
Sunday (or you can choose Thursday, if you're a rebel):
Note: This will just affect the date picker you use for events and to-dos. It will not affect other accounts you're on, so if you have multiple Basecamp accounts, you'll need to select this option in each account.
