Time now in Gradec

Gradec sits at latitude 42.89, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 39m is one point on that curve, not a fixed value.

Sunrise today lands at 06:40 and sunset at 08:20 local time, giving 13h 39m of daylight. Those figures come from the city's own coordinates (42.89, 23.23) rather than a country-wide average, so they match what you would actually see from a window in Gradec.

If you are coordinating from another country, the shortcut is the working window: a normal Gradec day of 09:00–17:00 falls between 06:00–14:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
