More exciting that it could be:
UPDATE events SET date_starts = DATE_ADD(date_starts,INTERVAL amountofdays DAY) WHERE event_id = 3;

amountofdays is the name of the column in the same table;
thus date_starts could be calculated depending on special amountofdays meaning for each row.

Nice! Wouldn’t have occurred to me that MySQL had such a feature. Personally I prefer to do all my data arithmetic in seconds before handing the result over to an SQL query, but this is worth noting.
