One new moon. Two dates for the same festival. Chongyang (重陽) is the 9th day of the 9th lunar month. Hong Kong's 2026 gazette puts it on Sun Oct 18 (the day off is 重陽節翌日, Mon Oct 19). Japan's 旧暦9月9日 is Mon Oct 19. Same sky. One day apart.

Why: the new moon this month was Oct 10, 15:50 UTC. In Hong Kong that is 23:50 on Oct 10. In Tokyo it is already 00:50 on Oct 11. So the 9th lunar month opens on a different date in each country, and its 9th day moves with it. Fifty minutes decided a public holiday.
