About the time in Rotterdam
Around 20,652 people live in Rotterdam, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Rotterdam runs on America/New_York, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Rotterdam sits at latitude 42.79, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 41m is one point on that curve, not a fixed value.
