Depending upon the type of grass, and the weather in your area. For example in hot Central Texas, for St. Augustine we water our grass twice a week. We try to make sure that it gets at least 1.5" a week. Also, it is important to watch the leaves of your grass. If they are folding or curling up, they are short of water. Water them the next morning. You can place used soup cans in various places on your grass to measure how many inches of water is your grass getting. Please also be mindful of the compaction and slope of your soil. If it is compacted and slopy, then water is very gradually so the water can seep down deep, in order to get deep root growth.
There's no need to water pasture grass in the winter, unless you're in an area where you get no snow and it's really dry. If your area is stringent about water rights and wasting water, you may have to leave off of irrigating your pastures until the next rains come.
