I thought you were thinking of countries like Thailand that has different numbering for the years.

> Thailand mainly uses the Buddhist calendar, in which the calendar's epochal date (Year zero) was the year in which the Buddha attained parinibbāna. This places the current year at 543 years ahead of the Gregorian calendar. The year 2022 CE is indicated as 2565 BE in Thailand. Despite adopting ISO 8601, Thai official date is still written in D/M/YYYY formats, such as 30 January 2565 BE (2022 CE) or 30/1/2565.
