So every company in Japan has their own public holiday, and they've written it down _somewhere_. Sounds easy compared to what the middle east has to offer on that account:
- When Dubai was awarded the 2020 World Expo the following day was declared public holiday (yes, less than 24 hours notice)
- In the UAE, the death of a Sheik is often followed by 3 days of mourning where government offices are closed (this can include a lot of office workers one might not think of as "government", as the respective emirates runs a lot of companies)
- When Qatar scored a goal at the world cup, a public holiday was immediately announced for the following day.
- Even planned public holidays, such as Ramadan (not a public holiday as such, but work does grind to a near halt) and Eid are determined by sightings of the moon, and the start and length of these are often announced days in advance.
