{{main|Thai six-hour clock}}

In [[Thailand]], [[Laos]], and [[Cambodia]], the traditional system of noting hours is the [[Thai six-hour clock|six-hour clock]]. This reckons each of a day's 24 hours apart from [[noon]] as part of a fourth of the day. The first hour of the first half of daytime was 7 am; 1 pm the first hour of the latter half of daytime; 7 pm the first hour of the first half of nighttime; and 1 am the first hour of the latter half of nighttime. This system existed in the [[Ayutthaya Kingdom]], deriving its current phrasing from the practice of publicly announcing the daytime hours with a [[gong]] and the nighttime hours with a [[drum]].{{sfnp|Thongprasert|1985|pp=229–237}} It was abolished in Laos and Cambodia during their [[French Indochina|French occupation]] and is uncommon there now. The Thai system remains in informal use in the form codified in 1901 by [[King Chulalongkorn]].<ref>{{citation |contribution=ประกาศใช้ทุ่มโมงยาม |title=Royal Gazette, ''No. 17'' |date=29 July 1901 |url=http://www.ratchakitcha.soc.go.th/DATA/PDF/2443/018/206.PDF |page=206 |access-date=8 March 2017 |archive-url=https://web.archive.org/web/20120609235147/http://www.ratchakitcha.soc.go.th/DATA/PDF/2443/018/206.PDF |archive-date=9 June 2012 |url-status=dead }}. {{in lang|th}}</ref>
