Plan Sleep Around Fajr
Use your local prayer timetable as an anchor and subtract the time you expect to spend awake. Protect enough total sleep before choosing a cycle-based bedtime. Prayer times change by city and season; this guide does not publish a universal Fajr time for Pakistan.

| Pattern | Sleep windows | Planned awake time |
|---|---|---|
| Earlier bedtime | 9 pm–5 am | Prayer after the sleep window |
| Split window | 10 pm–5 am; 5:30–6:30 am | 30 minutes between windows |
Work backward from your obligations
Write down the actual local prayer time, travel or preparation time and when work or school starts. Then choose a sleep window that fits your age-appropriate need. The schedules above are arithmetic examples, not a recommendation that 5 am is the current prayer time or that either pattern suits everyone.
Choose an earlier bedtime when practical
An earlier first sleep window avoids relying on a second window that may be interrupted by commuting, childcare or household noise. Allow time to settle; eight hours in bed is not automatically eight hours asleep. If a late evening is unavoidable, review the next day's obligations before assuming you can recover the difference.
If you return to bed after prayer
Plan how much time is available and account for falling asleep again. A short or noisy second window may provide less rest than its clock length suggests. Fixed 90-minute cycle estimates do not guarantee a particular sleep stage or a refreshed awakening. Note whether the arrangement actually leaves you alert over several days.
Check the routine against daily life
Keep the pattern reasonably repeatable and make space for a quiet wind-down. If daytime naps delay your next bedtime, reconsider their timing. Ongoing fatigue or repeated sleep disruption should be discussed with a clinician; adding more calculator cycles does not diagnose or treat the cause.
Frequently asked questions
Is Fajr always at 5 am?
No. Use a trusted timetable for your city and date. The times on this page are examples only.
Must I sleep in 90-minute blocks?
No. The cycle length is a simplified calculator assumption; adequate sleep and a workable routine matter.
Should everyone go back to sleep?
No. Work, family obligations, sleep quality and individual need determine whether a second window is practical.
