I am a little confused about your restriction- after doing some research this is what I'm seeing:
Limits outdoor watering to two days a week on an odd-even schedule. Even numbered addresses may water Wednesdays and Saturdays (4 p.m. to 10 a.m.); odd numbered addresses may water Thursdays and Sundays (4 p.m. to 10 a.m.). No water for outdoor fountains, car washes or power washing of homes.
Found that here: http://www.ajc.com/weather/possible-drought-restrictions-for-metro-atlantans/mYEBKDof6ejAmekx9LmLoO/.
If this is correct, I would use a Fixed Days schedule and allow watering on whichever two days are allowed for your address. If not, let me know what the restriction is and I can help you out!
