I ate 500 calories over maintenance today? Will I get fat?

I usually eat 1500 calories a day, but today I had close to 2000 calories. Will I get fat? Should I eat 1000 calories tomorrow to compensate for the extra 500 calories from today?

If I eat 500 below maintenance tomorrow, will that reverse the damage?
