How this service works
Bedtimes for a wake-up time, or wake times for a bedtime, using 90 minute cycles plus a fall-asleep allowance. Planning only.
Output
An ordered list of sleep options, each with the target bedtime or wake time, number of sleep cycles, total hours in bed, and hours of actual sleep. Also includes a summary, a verdict on the best option, a disclaimer about planning-only use, and metadata like cycle length and fall-asleep allowance used.
Example use cases
Early morning meeting sleep planner
“I have a work call at 7:00 AM and need to know what time I should go to bed tonight to wake up feeling rested — show me bedtime options using 90-minute sleep cycles.”
Custom bedtime with later wake window
“If I go to bed at 11:30 PM, what are the best times for me to wake up? Use 90-minute cycles, assume 20 minutes to fall asleep, and show me at least 3 and up to 5 options.”
Shift worker sleep optimization
“I work a night shift and usually get into bed around 8:00 AM — what wake-up times should I target based on sleep cycles, using a fall-asleep time of 10 minutes?”
Technical details
Endpoint
GEThttps://focus-sleep-calc.x402tookit.com/sleep-cycles?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to calculate multiple optimal bedtimes or wake times for a given anchor time using sleep cycle logic. Prefer it over generic calendar or alarm tools when the user specifically wants cycle-based sleep planning with configurable parameters like cycle duration and fall-asleep allowance. It is planning-only and does not set alarms or interact with device clocks.
Side effects
- Missing required 'know' parameter (wake or bed) returns an error
- Invalid time format not matching 12-hour or 24-hour patterns may cause a parse error
- minCycles greater than maxCycles produces no valid options
- cycleMinutes out of range (below 60 or above 120) rejected
- fallAsleepMinutes out of range (above 120) rejected
