Here's a quick MySQL tip I wanted to throw your way. I created an event system a while back and one of the requirements of the system was to show events that happened yesterday forward, meaning events older than 2 days were to be hidden. MySQL's date_add will allow you to do just that:
The MySQL Example
SELECT title, venue, url, city, state, DATE_FORMAT(date_starts,\'%b %e\') as formatted_date FROM events WHERE date_starts >= DATE_ADD(NOW(), INTERVAL -1 DAY) // yesterday! ORDER BY date_starts ASC
Note that I'm using a negative date value. You can use a positive date value to get tomorrow, next week, next month, etc..
I like the idea of showing events the from past few days -- they show that there's been action recently. Click here for more about MySQL date_add.
