The Timezone Fast Shifter helps you navigate international travel without breaking your intermittent fasting schedule. By calculating the impact of timezone deltas on your biological clock, it determines if a flight will cause an early feeding window or extend your fast beyond safe limits. Use calculate_fast_window_shift to find your new feeding time, validate_travel_timeline to check itinerary compatibility, and get_fast_fasting_safety_thresholds to monitor your safety boundaries.

I'm flying from New York (UTC-5) to London (UTC+0). My fast started at 2023-10-01T20:00:00Z. My flight leaves at 2023-10-02T10:00:00Z and lasts 7 hours. What is my new feeding window?

Your new feeding window start in London is 2023-10-02T17:00:00Z. The timezone shift has been accounted for.

Is my travel itinerary valid? Fast start: 2023-10-01T18:00:00Z, Flight departure: 2023-10-01T15:00:00Z, Duration: 5 hours.

No, the timeline is invalid because your flight departure occurs before your fasting start time.

What is my maximum safe fasting duration for a strict risk profile?

For the strict risk profile, your maximum safe fasting duration is 16 hours.

The `calculate_fast_window_shift` tool calculates the total elapsed time from your fast start to arrival, then adjusts for the destination's UTC offset to provide a new feeding window.
