Template:JULIANDAY

This template computes the number of the Julian day starting at noon on the date given in parameter (in the gregorian calendar, without the julian correction for proleptic years).

Syntax :

{{JULIANDAY|year|month|day}}

• The year must be astronomical (year=1 in 1 AD (Anno Domini), year=0 in 1 BC, year=-1 in 2 BC).
• The month is expressed between 1 et 12 from january to december.
• The day is normally between 1 et 31 (but offsets are possible for computing other days).

Note :

The julian day, when computed modulo 7, grows from 0 (on monday at noon) to 6 (on sunday at noon)) and falls back to 0 (on next monday). This corresponds to the order of days in the ISO week.

Examples :

{{JULIANDAY|-4713|11|24}} returns 0 (an 4714 av. J.-C., proleptic)

{{JULIANDAY|0|1|1}} returns 1721060 (an 1 av. J.-C., proleptic)

{{JULIANDAY|0|12|31}} returns 1721425

{{JULIANDAY|1|1|1}} returns 1721426 (Anno Domini, proleptic)

{{JULIANDAY|1752|2|29}} returns 2361024 (last proleptic day)
