Really depends on weather and to some degree grass type. It is hot and unseasonably dry here right now so I run each zone twice (24 minutes), 3 days a week right now. During rainy season I am normally 1 day / week just to make sure the pump for the well runs and sprinklers get used. When it is dry but less hot (winter), 1-2 days / week.
General rule is to run as little as possible and let the grass grow deep roots in search of water. Water deeply, less often. But there are times you need to supplement the weather. You can measure what it’s getting or get a smart timer if you want to really stay in top of it.
