Hi mckynzee, from LADWP's website:
"Based on the last number of your street address, your watering days are as follows:
ODD: Mondays, Wednesdays, and Fridays
EVEN: Tuesdays, Thursdays, and Sundays
Watering with sprinklers is limited to one cycle of up to 8 minutes per station per watering day for non-conserving nozzle sprinkler systems (typical residential system), or two 15-minute cycles per watering day for conserving nozzle sprinkler systems. ALL outdoor watering is prohibited from 9:00 a.m. to 4:00 p.m. regardless of the watering day."
I will be converting to rotary nozzles soon, so it won't be as big an issue, but until then...
