Quick Islamic Midnight Calculator
Enter your local Maghrib and Fajr times to find Islamic midnight (nisf al-layl), calculated as the midpoint of the night.
What is Islamic midnight?
In Islamic timekeeping discussions, “midnight” often refers to the midpoint between Maghrib and Fajr, not 12:00 AM on a civil clock. This is commonly called nisf al-layl (half of the night).
Because night length changes through the year, Islamic midnight changes too. In summer, it may be later; in winter, it may be earlier.
How this calculator works
The calculator uses a straightforward formula:
- Night starts at Maghrib.
- Night ends at Fajr (next dawn).
- Islamic midnight = Maghrib + half of night length.
Formula
Night length = Fajr (next day) − Maghrib
Islamic midnight = Maghrib + (Night length ÷ 2)
For added benefit, this page also shows:
- Start of the last third of the night
- Total night duration
- A simple day marker when times pass midnight
Why people calculate it
Muslims often want this value for practical worship planning, such as understanding nighttime timing windows and organizing prayer routines. It also helps with personal schedules, sleep planning, and setting reminders for late-night worship.
Step-by-step usage
- Open your local prayer timetable or trusted prayer app.
- Enter the Maghrib time for today.
- Enter the Fajr time for the following dawn.
- Click Calculate.
- Read Islamic midnight and related night timing points.
Example
If Maghrib is 18:00 and Fajr is 06:00:
- Night length = 12 hours
- Half of night = 6 hours
- Islamic midnight = 00:00
If Maghrib is 17:35 and Fajr is 05:10:
- Night length = 11 hours 35 minutes
- Half = 5 hours 47.5 minutes
- Islamic midnight ≈ 23:23
Common mistakes to avoid
- Using civil 12:00 AM as “Islamic midnight” without checking Maghrib/Fajr.
- Using Fajr from the wrong date (always use the next dawn).
- Mixing timetables from different calculation methods or locations.
- Ignoring daylight saving time changes.
