Holocene Epoch Timestamp is a Chrome extension that adds or replaces timestamps on webpages with Holocene Epoch timestamps. This allows users to better grasp the development of human civilization by setting the first year of the 'recent' epoch 10,000 years before the first Anno Domini (1 AD). The extension is currently powered by Regular Expression matching and future versions will include Natural Language Processing for improved accuracy.

The Holocene Epoch sets the first year of the "recent" epoch 10,000 years before the first Anno Domini (1 AD) for a better grasping of the development of the human civilization. The proposal was advanced by Cesare Emiliani in 1993 (see more in the What is the Holocene Epoch? of the extension).
e.g.
"1 Aug. 2023" can become "1 Aug. 2023 [12023 HE]";
"399 BC" can become "/9602 HE/ 399 BC";
"10 Sep. 259 BC" can become "10 Sep. 9742 HE".
To Be Developed
The alpha/beta version is powered by Regular Expression matching and some compromises have been made. Future iterations will match through Natural Language Processing.
User reviews
It's good to be fair, but have some flaws: the years from: (11900 to 11909), (12000 to 12009), sporting seasons like: (12000-01, or 12008-09), doesn't convert well, the first decade of every century doesn't convert properly, instead remains 1900-1909, 2000-2001, also some other ancient years, milleniums, doesn't convert adequately, can you fix this please? aside form that, this is something I was looking for a while ago, good effort.
I have been looking for something like this.
The only thing that I want to point out is that if you have something like:
https://en.wikipedia.org/wiki/Ancient_Egypt
Early Dynastic Period (c. 3150–2686 BC [7315 HE])
It only converts the last date. (2686 BC)
You should do something that detect "3150–2686 BC", numbers that are atached with a "-".
So that it converts to "6851-7315 HE".
Can you please look into this, thanks.
