Practical Example

Imagine you need to wake up at 7:00 AM for work. Inputting this wake-up time into the calculator generates optimal bedtimes based on full sleep cycles. The calculator might suggest:

• 10:00 PM
• 11:30 PM
• 1:00 AM

These options help ensure you complete full sleep cycles, making it easier to wake up refreshed.

Alternatively, if you plan to go to bed at 11:00 PM, the calculator could recommend wake-up times such as:

• 6:00 AM
• 7:30 AM
• 9:00 AM

This flexibility allows you to adjust your schedule according to personal needs and lifestyle.
