Night shift sleep schedule calculator
Enter your shift times and commute. We'll build a sleep window that fits whole sleep cycles, with an optional anchor nap and a caffeine cutoff, so your days off don't wreck your nights on.

Principles of a night shift sleep schedule
- Sleep as soon as you can after the shift. Sleep pressure is highest then, and the morning is quieter than the afternoon. The calculator schedules sleep 30 minutes after you get home.
- Protect it like a night. Blackout curtains, a cool room, phone on do-not-disturb, and a sign on the door. Earplugs or white noise for daytime sounds.
- Control light. Bright light during the first half of the shift helps alertness; dark glasses on the commute home stop morning sun telling your clock it's daytime.
- Nap before the shift. A 20-minute nap before a night shift improves alertness; NIOSH training for shift workers recommends planned naps.
Days off and rotating shifts
On days off, many night workers use a split pattern: sleep a shorter block in the morning after the last shift, then go to bed at a normal-ish time. Keeping an "anchor" of 4 hours that overlaps your work-day sleep — for example 8 am–12 pm on nights on and 4 am–12 pm on days off — helps some people switch faster.
If you rotate, forward rotation (days → evenings → nights) is generally easier to adapt to than backward rotation.
Questions people ask
What is the best sleep schedule for night shift workers?
For a 10 pm–6 am shift with a 30-minute commute, a common pattern is sleeping from about 7 am to 2:45 pm (five cycles), then a 20-minute nap around 8:30 pm before leaving. Consistency on work days matters most.
Should I sleep before or after a night shift?
Most people do best with their main sleep right after the shift, when sleep pressure is high, plus a short nap before the next shift. Some prefer sleeping in the afternoon; the key is keeping it consistent.
How do I switch back to days on my days off?
Sleep a short block (3–4 hours) after your last night shift, stay up through the afternoon with daylight, and go to bed at a normal evening time. That keeps an anchor and limits the swing.
How much sleep do shift workers need?
The same 7–9 hours as other adults, though daytime sleep is often shorter and lighter. A planned nap can make up part of the gap.
