Archaeologists in Vietnam discover what is thought to be a lunar calendar – a stone tool carved with 23 lines – in Northern Vietnam.

Ancient calendar unearthed
Vietnam Net, 27 Sep 2012
Archaeologists have found a stone tool assumed to be an early calendar dating back 4,000 years in a cave in the northern province of Tuyen Quang.
The stone tool, with 23 parallel carved lines, seemed to be a counting instrument involving the lunar calendar, Prof Trinh Nang Chung from the Viet Nam Archaeology Institute told Viet Nam News.
A similar tool was found in Na Cooc Cave in the northern province of Thai Nguyen’s Phu Luong District in 1985, Chung said. Similar items have been found in various areas in the world, including China, Israel and the UK, suggesting that people 5,000 years ago knew how to calculate the lunar calendar by carving on stones.
