You can specify what day should be displayed as the first day in the week when displaying information in the Days column of the Stations tree table, in the Days field on the Query toolbar, and in the current day field on the status bar.
On the View menu, point to Days, and then select either Start with Sunday or
Start with Monday on the submenu.
You can also select the display style for the days of week on the context menu, which you can open with a right‐click on the current day field on the status bar.
Note that the setting that you selected may change later, when you switch to a different interface language.
