Couple of comments: The URL days.to is cool, but from a comprehension point of view if the event is more than a month away, should start using weeks, then months, then years. Filtering by locale would be helpful There is lots of open source data on astrological events: eclipses, NASA satellite fly by's, etc. Gamification. Allow users to submit photos for each event and allow all users to vote them up and down. Props for users with most or best photos. Or allow users best place to be on that particular event. Again, allow users to vote best up or down.
