How to Check Holidays for Thirteen Regions: And Why Mainland China's Make-up Workdays Need Special Treatment

Select a Region, and Holidays Overlay the Calendar

At the top of the Almanac calendar, there is a row of region options. After checking a box, that region's official holidays for the current month are directly marked in the date cells. The selection is stored locally in the browser and is not uploaded to the server. Multiple regions can be checked at once, making it convenient to compare holidays in different places simultaneously. For example, an office worker in Taiwan wanting to know which days a Japanese client is off can simply check both boxes.

There are currently thirteen regions available for selection: Mainland China, Taiwan, Hong Kong, Macau, Singapore, Japan, South Korea, the United States, the United Kingdom, Malaysia, Thailand, Indonesia, and Australia.

Nine Verified, Four Still in Progress

As of 2026, data has been verified against official announcements and entered for nine regions: Mainland China, Taiwan, Hong Kong, Macau, Singapore, Japan, South Korea, the United States, and the United Kingdom. This means that for these nine regions, each holiday entry has been individually compared against the calendars published by their respective governments, and each entry is marked with its verification status.

The other four regions—Malaysia, Thailand, Indonesia, and Australia—have not yet been entered. The reason is not a lack of data, but rather that the official holidays in these countries involve a choice regarding administrative levels: some holidays are uniform at the federal or national level, while others apply only in specific provinces or states. A consistent method of presentation requires first deciding which level to use as the standard. Rather than launching hastily and causing confusion, it is better to establish the rules first before entering the data.

'Not Found' Is Not the Same as 'Not Yet Entered'

This is a distinction made deliberately by this site.

The common practice is: if there's no data, display nothing. The problem is that on screen, 'a date on the calendar with no holiday marker' and 'that date is genuinely not a holiday' look identical. If a user checks holidays for 2027 and sees a date with no marker, it is easy to simply assume that day is a workday and plan accordingly. In reality, it might be that we haven't entered the 2027 data yet.

Therefore, when a user views a year whose data has not yet been verified, a clear notice appears stating that the holiday data for that year has not been entered. This is fundamentally different from 'the official announcement says that day is not a holiday.' Displaying them separately is to prevent users from making incorrect schedule arrangements based on incomplete information.

Each holiday entry that has been entered is also marked with whether it has been verified against official announcements. Users can judge the credibility of the data for themselves.

Mainland China's Make-up Workdays Require Special Handling

Mainland China's holiday arrangements have a structure rarely seen in other regions: to create consecutive long holidays, the government adjusts the surrounding weekends to become workdays, a process called 'tiáo xiū bǔ bān' (調休補班) or adjustment and make-up work. In other words, a certain Saturday or Sunday, which would normally be a day off, becomes a workday due to this adjustment.

These 'make-up workdays' (bǔ bān rì) are not holidays in nature, but rather 'weekends on which attendance is mandatory.' If they are displayed alongside holidays, or simply not displayed at all, mainland users checking the calendar would see an unmarked weekend and assume it's a normal day off—only to not show up for work that day.

This site's approach is to mark make-up workdays in a different color and write 'bǔ bān' (補班) directly in the cell. This is clearly distinguished from the display method for holidays, allowing users to see at a glance: although this day was originally a weekend, it is a workday.

This is also one of the items most frequently queried by mainland users. The consequence of an error is very concrete: missing a day of work. Among all holiday-related information, make-up workdays have the highest cost of error, so their display logic must be handled independently and cannot be mixed with other holidays.
