Check the result at tycho.usno.navy.mil after purging this page. Usage: {{MJD}} = {{YMD2MJD}} + {{dectime}}.; {{MJD|year | month | day|hours | minutes | seconds}} converts a specified date.; {{MJD|year}} = {{MJD|year | 01 | 01 | 00 | 00 | 00}}.
Examples: {{MJD|-4712|1|1}} = -2399999 (JD = -0.5, for proleptic Julian calendar date); {{MJD|-4712|1|1|12}} = -2399998.5 (Julian Day 0 at noon); {{MJD|1858|11|17}} = 0; {{MJD|1969|12|31|23|59|59.98}} = 40586.999999769; {{MJD|1969|12|31|23|59|59.99}} = 40586.999999884; {{MJD|1970}} = 40587; {{MJD|2024}} = 60310; {{MJD|2024|01|01|00|00|00.01}} = 60310.000000116; {{MJD|2024|01|01|00|00|00.02}} = 60310.000000231
Accuracy: {{#expr:({{MJD|2007|01|01|00|00|01}}-{{MJD|2007|01|01|00|00|00}})*86400}} = 0.99999331869185, good enough for 1/100 seconds, but not milliseconds.; {{MJD2HMS|0.99999331869185/86400}} = 00:00:01
