How this differs from the Sleep Calculator
Our standard Sleep Calculator only gives you times based on strict 90-minute intervals to avoid waking up mid-cycle. This Bedtime Calculator is for when you simply want to know when to get in bed to achieve a specific number of hours of sleep, regardless of cycles.
