About this extension

Add the Holocene Epoch timestamp (2027 CE becomes 12027 HE) before or after the timestamps present on the webpage (or replace them).

Read the publisher’s full description

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.

Hi Jan Cavel, people who are visiting www.easytimeline.org and linking to your Holocene Epoch Timestamp are enjoying it! And analytics say visitation has increased. Your Holocene Epoch Timestamp makes wikipedia so easy to use! Your HE Timestamp concretely recognizes and labels the flowing HE timeline. Bravo! Today, doing a search wikipedia even labeled the date as "94th Century HE"! Thank you for your continued efforts!

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.
