About the lunisolar calendar

1. Site of the discovery: The calendar has been discovered at Göbekli Tepe. It is an ancient site in southern Turkey. The site is known for its temple-like enclosures, and this discovery adds to its significance as one of the most important archaeological sites in the world.

2. Significance of the Calendar: The calendar documents a significant astronomical event, a comet impact that occurred around 13,000 years ago. This event is believed to have had a profound effect on Earth, possibly triggering a 1,200-year ice age and leading to the extinction of many large animals.

3. Carvings on the Pillars:  The pillars at Göbekli Tepe contain detailed carvings, including V-shaped markings. Scientists suggests that these carvings record the date and story of the comet fragments that struck Earth around 10,850 BC. The V-shaped symbols are thought to represent days in a lunisolar calendar.

4. Cultural and Historical Impact: The carvings suggest that ancient people were capable of observing and recording the movements of the sun, moon, and constellations, marking seasonal changes and significant events.
