Need to add the feature to allow people to add special weekend days as working days in the calendar. Currently, you can only set the recurring working days and holidays in the calendar.
Every year the Chinese government will issue the special arrangements for weekends adjacent to some public holidays like the National Day and Labour Day. For those holidays, the adjacent weekends will become working days in exchange for a longer continuous holiday afterwards. It is called 调休 in China.
For instance, in 2019, the National Holiday is Oct 1-7, while Sept 29 (Sunday) and Oct 12 (Saturday) are working days.
Missing this feature makes it difficult to manage working days for companies in China. As a workaround, they may need to manage two calendars to calculate the correct working days.
