Therefore, keep watch, for you do not know when the lord of the house is coming back, whether during the evening watch, or the midnight watch, or the rooster-crowing watch, or the morning watch.a Bible see other translations
In NT times, the rooster-crowing watch was from midnight to 3 a.m.

“during the evening watch.” At the time of Christ, in both Jewish and Roman reckoning of time, the “day” was divided into 12 hours (John 11:9, “Are there not 12 hours in the day?). Also, both the Jews and Romans divided the night into four “watches,” each being three hours long. This was true even though the Jews started their new day at sunset, at the start of the first watch of the night, and the Romans reckoned their new day at midnight, at the start of the third watch of the night (our day beginning at midnight comes from the Romans). In New Testament times, the day was divided into 12 “hours” (John 11:9) and the night into four “watches”: 1st: 6-9 p.m.; 2nd: 9 p.m.-midnight; 3rd: midnight-3 a.m.; 4th: 3-6 a.m. (Mark 13:35).

The names of the four watches are named in the commentary on Mark 6:48, and were “evening watch,” “midnight watch,” “cockcrowing watch,” and “morning watch.” Sometimes, however, the watches were just called by “first watch,” “second watch,” “third watch,” and “fourth watch.”
