Time Calculation Methodology

Time-zone rules can change through political decisions. Results depend on the browser's IANA time-zone data and may be less reliable for distant future or historical dates.

The planner converts local midnight in the first city to UTC and generates candidates at the selected interval. Every city row represents the same UTC instant.
