Sleepy Bedtime Calculator

What is Sleepy Bedtime Calculator ?

sleepytime (by somnia) is a minimalist bedtime calculator designed to eliminate morning grogginess by aligning your alarms with natural 90-minute sleep cycles. Instead of just counting hours, the tool works backward or forward in 90-minute increments from your target time, building in an adjustable 15-minute buffer for the time it takes to fall asleep.
