Tahajjud time calculator
See when the night prayer can be offered, from Isha through to Fajr, with the midpoint and the last third marked out for your location and date.
What this marks out
The window in which the night prayer can be offered: from Isha until Fajr. Inside it, two points are shown because they are the ones people ask about, the midpoint of the night, and the start of its final third.
Those divisions are of the whole night, measured from Maghrib rather than from Isha. That is the conventional way the night is divided, and it puts the boundaries earlier than dividing the window would.
Why the window is shorter than the night
The night runs from Maghrib; the window does not open until Isha, an hour or two later depending on the season and the calculation method. Both figures are shown so the difference is visible rather than implied.
Which night a date refers to
A night belongs to the evening it starts in. Choosing a date gives you the night that begins that evening and ends at the following morning’s Fajr, so the calculation looks at two days and takes the later Fajr, rather than the same day’s, which would describe the previous night.
What this tool does not do
It does not tell you when you should pray, or rank one part of the night above another. Those are questions with a scholarly literature behind them, and a calculator has nothing useful to add to it. What it can do is tell you accurately where the night falls tonight, where it divides, and when it ends.
