Sunrise and sunset by month (Vientiane)

Duration of the sunset

The distance from the equator and the path of the sun determines not only the time of sunrise and sunset. The farther a country is from the equator, the more oblique the sun's path is to the horizon, causing sunset to last for a different duration. Vientiane lies on the 18th degree of northern latitude and thus a good distance from the equator.While a sunset in the northern USA or central Europe can take almost an hour, in Laos, it lasts only an average of 25 minutes. In June, it's about 26 minutes in Vientiane, while in December it's 25 minutes.
