May 1, 1900.
This day is International Labour Day, established back in 1889 by the Second International to commemorate the May Day strike by workers in Chicago, United States.
It's worth mentioning that May 1 in East Africa is also Labour Day because of Ernst, just without the international qualifier. Furthermore, East Africans will celebrate May Day along with a National Day holiday, as Ernst decided to extend East Africa's May Day holiday from three days to seven days, making it a week-long celebration.
East Africa itself is a country with relatively few holidays. As a new nation, Ernst abolished some European religious holidays. East Africa doesn't experience a clear winter, and its territory is split by the equator into two parts, which means East Africa doesn't have a unified nationwide slack season. Therefore, to minimize interference with agricultural activities, many traditional Europe and Asia holidays do not resonate in East Africa.
