I got a calendaring app and a terminology question.
An event that occurs just once, is a one-off
If it occurs every second Monday, and/or 4th Friday of month it is regular
If it happens on a random series of odd days, it is irregular
But if it starts on 12-jan and runs every weekday until 3-mar and never happens again (like a museum exhibiton), it is what-non-technical-one-word?
