Ephemerides are content that varies by date. They are used for several different purposes:
- Display a message that is only valid for a specific day. (Happy Birthday Bono!)
- Stage content so that something new appears on the site every day, or on specific days
- Countdowns to important events (Only 7 days left to register for the Installfest!)
Ephemerides have been discontinued as of version 2.0.
