Bolivia has an east-west extension of 11.4 degrees of longitude. Given the country's location in South America, this corresponds to about 1200 kilometers. With this still relatively small extension, the course of the sun is only slightly different at different positions in the country. The position of the sun in the west of the country differs from that in the east by only about 46 minutes. This means the sun rises and sets 46 minutes later in the west than in the east.

No more daylight saving time in Bolivia

Due to the sun's orbit around the equator, the days are longer in summer (November to February in the southern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to the relative proximity to the equator, the impact in Bolivia is not particularly large. Sucre is only 2,100 km from the equator. A day in midsummer would then not last from 05:40 to 18:59, but from 06:40 to 19:59. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, in 1932, the decision was made to finally abandon daylight saving time in Bolivia.
