Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

sleepTime6 = waking_up_time - first_cycles_length - next_cycles_length × (6 - 1) - falling_asleep_time

sleepTime5 = waking_up_time - first_cycles_length - next_cycles_length × (5 - 1) - falling_asleep_time

sleepTime4 = waking_up_time - first_cycles_length - next_cycles_length × (4 - 1) - falling_asleep_time

sleepTime3 = waking_up_time - first_cycles_length - next_cycles_length × (3 - 1) - falling_asleep_time

sleepTime2 = waking_up_time - first_cycles_length - next_cycles_length × (2 - 1) - falling_asleep_time

sleepTime1 = waking_up_time - first_cycles_length - next_cycles_length × (1 - 1) - falling_asleep_time

The calculator uses 60 further relationships to link its other values.

Each cycle lasts approximately 90 minutes, and completing multiple cycles throughout the night improves the quality of restorative sleep.

How does the 90 Minute Sleep Cycle Calculator work?
