Sleep Cycle Calculator
Find better bedtimes, wake-up times, naps and sleep schedule
A free online Sleep Cycle Calculator that helps you plan bedtime and wake-up times around approximate 90-minute sleep cycles. It also includes a nap calculator, caffeine cutoff, sleep debt, recommended sleep by age, sleep quality check, weekend recovery planner and jet lag adjuster — all in one simple browser tool.
Hi Product Hunt! 👋
I built Sleep Cycle Calculator as a free browser-based tool for people who want a simple way to plan their sleep schedule.
Instead of having separate tools for different sleep questions, I wanted to bring several useful calculators together in one place:
🌙 Bedtime Calculator
⏰ Wake-Up Time Calculator
😴 Nap Calculator
☕ Caffeine Cutoff Calculator
📉 Sleep Debt Calculator
🎂 Recommended Sleep by Age
✅ Sleep Quality Quick Check
🛌 Weekend Recovery Planner
✈️ Jet Lag Adjuster
The main calculator uses approximate 90-minute sleep cycles and includes a 15-minute estimated fall-asleep buffer.
The goal is to make sleep timing easier to explore without installing an app or creating an account.

I'd love to hear your feedback. Which sleep-related calculator or feature would you like to see added next?
