Henrick Yau
Senior Editor, Time & Astronomy
Singapore
Henrick Yau has been writing about time, astronomy, and calendars at time.now for more than four years. His work covers the mechanics of daylight saving time, the accuracy of prayer-time calculations at high latitudes, the physics of eclipses, and the accidents of history that shape why we measure time the way we do.
He reports on the big astronomical moments as they happen — total solar eclipses, meteor showers, supermoons, equinoxes — but is just as interested in the small, strange details: why the sun sets earliest two weeks before the winter solstice, why Samoa erased December 30, 2011 from its calendar, why the Hubble constant still can't be pinned down after 35 years of trying.
Based in Singapore, Henrick writes in English and occasionally in Mandarin. Before joining time.now he wrote science for newsrooms on three continents. He is particularly interested in how astronomical timekeeping translates across cultures — Hijri, Hebrew, Chinese, and Hindu calendars all treat time differently, and he believes readers deserve coverage that takes those traditions seriously.
