California watering schedules
Watering rules change at the supplier boundary, not the city limit sign, and most official pages bury them in PDFs. Every schedule here is read from the supplier’s own rules and ordinances, with sources and a verification date on the page.

Supplier not on this list
Start from the water bill rather than the address. The supplier that bills you sets the watering days, and it is often not the city named on the envelope. Search that supplier's name with the words watering schedule, and read the ordinance it links rather than the summary page.
The run time calculator covers 676 California cities, so it gives you the minutes wherever you are. It does not know which days your supplier allows, so set those yourself once you have found them.
