😴 Sleep Calculator – Find the Best Time to Go to Bed
Want to wake up feeling rested and energized? This sleep calculator helps you plan the best time to fall asleep based on your desired wake-up time. It uses 90-minute sleep cycles and includes 15 minutes to help you fall asleep. Choose the optimal bedtime so you wake up at the end of a cycle—not in the middle of one!
🌙 How It Works
Sleep happens in 90-minute cycles. If you wake up in the middle of deep sleep, you’re more likely to feel groggy. This calculator suggests bedtimes that align with the end of a full sleep cycle, helping you wake up feeling refreshed.
🕐 Why Multiple Bedtime Options?
Everyone’s schedule is different, so we give you a range of options. The earlier the bedtime, the more full sleep cycles you get. For example, if you need to wake up at 6:30 AM, your best bedtimes might be:
- 9:15 PM (6 full cycles)
- 10:45 PM (5 cycles)
- 12:15 AM (4 cycles)
- 1:45 AM (3 cycles)
- 3:15 AM (2 cycles)
- 4:45 AM (1 cycle)
Pick the bedtime that fits your schedule best. Each option includes 15 minutes to fall asleep.
💤 Understanding Sleep Cycles
Each 90-minute cycle moves through light and deep stages of sleep. Waking at the end of a cycle makes it easier to get up and feel alert. This tool helps you time your bedtime so you wake up at a natural break in your sleep pattern—no more feeling groggy or hitting snooze!
