If I get married at 2pm and want to have a dinner reception, what time should that start? Is it ok to have the ceremony at 2pm and the reception start at 5pm? Any other ideas?
Absolutely. You could include that information on the invitation or on a separate enclosure. If it is included on the invitation, please follow the same formality used in the rest of the message adding "reception to begin at 5 pm, destination title, The favor of a reply is requested, address. If it is included as a separate enclosure or invitation, it would read similarly to the wedding invitation only stating that the reception will held on date, time, location title, favor (or favour if it is formal), of a reply is requested, address.

In case you were wondering if it was appropriate to plan your reception to be held three hours after your wedding, yes. It is always better to have your reception soon after the wedding, but many times it is impossible.
It would be considerate to have some sort of activity or a room with refreshments set up in a near-by hotel for your out-of-town guests so they may wait comfortably. Rebecca Black, Etiquette Now
