-| **Date** shows the month, date, and weekday. e.g. `_2 _4 _0` for Sunday, February 4th. | You can choose month/date or date/month format in the options menu (2). Setting is done in three stages: first year, then month, then date.<br/>Weekdays are: 0=Sun, 1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat |
