What it means

Where is that on the timeline?

All dates are UTC. Unix time and these counts ignore leap seconds; Excel serials follow the 1900 date system and start at 1 March 1900.

The math

How to convert MJD to UTC

date = 1970-01-01 00:00:00 UTC + timestamp seconds. Excel serial = Unix ÷ 86,400 + 25,569; Julian Date = Unix ÷ 86,400 + 2,440,587.5.

Example: 54876 MJD = 2009-02-14 00:00:00 UTC.
