Wake Up Time Calculator
Calculate the best wake up time based on your sleep cycles. Understand sleep phases, sleep duration, and wake up feeling refreshed with optimal timing.
Step 1: Sleep Details
Understanding Sleep Cycles
Each sleep cycle lasts about 90 minutes and includes all sleep stages. Waking between cycles (at the end of a cycle) helps you feel more refreshed than waking during deep sleep.
Step 2: Personal Factors
Optimal Sleep Duration
Most adults need 7-9 hours of sleep per night, which equals 5-6 complete sleep cycles. The exact amount varies by age, genetics, and lifestyle factors.

Sleep Phase Analysis
Sleep Cycle Formula
Optimal Wake Time = Bedtime + (Sleep Cycles × 90 minutes) + Time to Fall Asleep
The optimal wake up time is calculated by adding complete sleep cycles (each 90 minutes) to your bedtime, plus your average time to fall asleep. Waking at the end of a cycle minimizes sleep inertia.
