Today's Hours by Planet in Hong Kong
Planetary Hours in Hong Kong Through 2026
Inside the tropics, the seasons barely stretch Hong Kong's planetary hours: the daytime hour moves only between 54 minutes (Dec 22) and 68 minutes (Jun 21).
Because Hong Kong lies between the tropics, the noon Sun passes straight overhead twice a year, on Jun 3 and Jul 10.
The shortest day is not the darkest at both ends: Hong Kong's earliest sunset comes 30 days before it, on Nov 22, and its latest sunrise 16 days after it, on Jan 7, because solar noon drifts through the year.
| In 2026 | Shortest / earliest | Longest / latest |
|---|---|---|
| Daytime hour | 53.9 min, Dec 22 | 67.5 min, Jun 21 |
| Sunrise (first hour) | 5:38 AM, May 31 | 7:04 AM, Jan 7 |
| Sunset (first night hour) | 5:38 PM, Nov 22 | 7:11 PM, Jun 26 |
How These Times Are Calculated
Twelve equal hours run from sunrise to sunset and twelve from sunset to the next sunrise, starting with the weekday's ruler and following the Chaldean order. Every time on this page, today's and the year's, is calculated for these coordinates with a high-precision ephemeris.
