There are usually two sessions - or periods - of play with an interval in between in a professional limited-overs match, to give both sides the same number of overs to bat.
Test Match, first-class and some recreational cricket usually has three sessions scheduled in a day's play, commonly known as the morning, afternoon and evening sessions. The morning runs from the start of play until the lunch interval, the afternoon from the resumption after lunch until tea, and the evening session from tea until close of play.
