The Hang of Thursdays

The Stage is a room. Rule for printing the name of the stage: say "[current weekday] [current time period]" instead.

A weekday is a kind of value. The weekdays are Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday. The current weekday is a weekday that varies. The current weekday is Saturday.

A time period is a kind of value. The time periods are morning, afternoon, evening, night. The current time period is a time period that varies. The current time period is afternoon.

This is the new advance time rule:

   if the current time period is less than night:

      now the current time period is the time period after the current time period;

   otherwise:

      now the current time period is morning;

      now the current weekday is the weekday after the current weekday.

The new advance time rule is listed instead of the advance time rule in the turn sequence rules.

Test me with "z / z / z / z / z".
