Sunrise and sunset in Thị Trấn Đông Triều

Each twilight begins at the morning time and ends at the evening one.

• Longest day: June 21, 13 h 25 min, from sunrise at 05:13 to sunset at 18:38.
• Shortest day: December 22, 10 h 51 min, from sunrise at 06:26 to sunset at 17:17.

• Sunrise and sunset are when the top of the Sun meets a level horizon, allowing for the usual bending of light by the air. Hills, buildings and height shift what you see by a few minutes.
• Civil, nautical and astronomical twilight end when the Sun is 6°, 12° and 18° below the horizon. Golden hour here is the photographers’ usual definition: the Sun less than 6° above it.
• Worked out when the page loads from NOAA’s solar equations, for 21.1° N, 106.5° E, and accurate to about a minute.
