The Holocene Calendar, a calendar beginning at about the start of visible effects of human activity on the earth (around 12,000 years ago), is easier to use, understand and teach because it has a year Zero.
Unlike most calendars, which begin their counts at some point in the history of one particular group, the Holocene Calendar is meant to include all of humanity. It’s also alot easier to teach kids history. More importantly, having an inclusive calendar means we all learn to think of ourselves as human beings, all living in the Holocene or Human Era.
(later edits: 1. an inclusive Calendar is a good start, imho, for re-framing the way we think and communicate, which works with NonViolent Communication to change our culture and thus our world and 2.
