Timezone settings determine how deadlines appear in your account and calendar. When you set up your account, your timezone is automatically set to UTC. You should ensure that your timezone is correctly set to your local time so that your due dates are always accurate for you. In your Timezone settings you can specify your week start day.
1. Go to your Personal Settings
2. Edit your timezone
Choose the time zone you're currently in and your week start day.
3. Update your settings
Select ‘Save changes’ to update your Timezone settings.
