Is it possible to get the calendar to start on a Monday.

Yes. To change the day your calendar week starts on:

1. Go to Manage Listings and open the listing you want to change.

2. Click Calendar.

3. Click Settings in the calendar toolbar.

4. Open the Advanced tab, then click Edit at the top right of the settings panel.

5. Under Calendar settings, set Calendar starts on to Monday.

The change saves as soon as you pick it, and it applies to that listing's calendar only - set it per listing if you have more than one.
