Two years ago Kurzgesagt proposed a new calendar that would start 10,000 years before the Common Era, around the time when agriculture started in the Fertile Crescent and the hunter-gatherers of Göbekli Tepe erected the world's first stone temple. They argued that this would be a more universal calendar than those in use today and would give a better appreciation of the time lapse since humans settled down. It would also greatly facilitate dating for archaeologists and historians, getting rid of the BC/BCE or BP terminology altogether for anything from the Neolithic/Mesolithic onward.

They have published their Human Era calendar for 2017, 2018 and 2019 (or 12,017, 12,018 and 12,019 HE). Please check the video.
