How do I know how many days I need to adjust?

You can use the `get_adjustment_duration` tool by providing the total timezone offset and your preferred daily shift limit.

Is there a safe limit for shifting my body clock?

Yes, you can use `validate_shift_capacity` to check if your proposed daily shift limit falls within a healthy physiological range.

Can I track my progress during the adjustment period?

Yes, the `calculate_sync_progress` tool allows you to see the percentage of adjustment completed based on days elapsed.
