Approximately when is the time of the last third of the night?

The middle of the night (jawf al-layl) is its last third, which is the fifth part of the night's sixths. It is calculated by dividing the hours of the night, from the Maghrib (sunset) call to prayer to the Fajr (dawn) call to prayer, into three thirds or six sixths. Thus, the middle of the night is the third third or the fifth part of the six sixths until the end of the night. This varies according to countries and seasons of the year.
