How does the calculation work?

The tool subtracts your estimated sleep latency from your target wake time, then subtracts the total duration of your desired 90-minute sleep cycles.

What is a sleep cycle?

A single sleep cycle lasts approximately 90 minutes. You can use `get_sleep_cycle_metrics` to see the total time required for a specific number of cycles.

Does it account for how long it takes me to fall asleep?

Yes, by providing your sleep latency in minutes, the `calculate_bed_time_schedule` tool ensures your schedule is accurate.
