The Julian date is a time format that is simply the number of days since noon UTC on Jan 1, 4713 BCE. This is a more human-centric version of the common computer format that counts the number of seconds since Jan 1 1970.
Example dates:
- 1705426.10000 - Assassination of Julius Caesar
- 2266295.90000 - Columbus lands in the Western Hemisphere
- 2440423.62240 - Apollo 11 moon landing
- 2460069.23991 - This repository uploaded to github
Breaking this down in to meaningful components:
246----.----- : Generation count. Each generation lasts 10,000 days, or 27.4 years: approximately one human generation. Thus, this repository was created 2 generations after the first moon landing and 76 generations after Julius Caesar.
---0069.----- : Day count.
-------.2---- : Metric hours: each one lasts 100 metric minutes or about two and a half hours.
-------.-39-- : Metric minutes: each one lasts 100 metric seconds or about a minute and a half.
-------.---91 : Metric seconds: ticks once every 864ms.
