How it works
Your browser's built-in time zone database converts each hour of the chosen date for every city, including daylight saving time on that specific date — so the result stays correct across the weeks when countries change clocks on different days. A city is shaded as working hours between the start and end you set, “early / late” for the two hours before and after, and night otherwise. “+1d” and “−1d” mean the local date differs from the first city's date. All calculations happen in your browser.
