In #Thailand, two main calendar systems are used alongside each other: the #ThaiSolarCalendar, based on the #GregorianCalendar and used for official and most day-to-day purposes, and the #ThaiLunarCalendar (a version of the #BuddhistCalendar, technically a #lunisolarCalendar), used for traditional events and Buddhist religious practices.

Ancient calendar, possibly world's oldest, found: Could it document a long-ago disaster? - Times of India

A researcher from the University of Edinburgh uncovered the earliest lunisolar calendar at Göbekli Tepe, an ancient site in Turkey. Martin Sweatman linked markings on a pillar to a comet impact 13,000 years ago, suggesting ancient people recorded this event. The discovery hints at advanced astronomical understanding of that time.
