Notes

Time zones use the IANA database (e.g., America/New_York). City shortcuts map to common zones like New York → America/New_York.
DST is determined by your browser’s `Intl` implementation for the selected date.
On DST change hours, some local times are ambiguous or skipped. This tool follows the database rules.
