Template:DOW

This template computes the ISO weekday number (1=Monday, 7=Sunday) for a given Gregorian date.

It has been especially useful for dates before January 1, 1970, because they were outside the range of #time.

{{DOW|2006|1|3}} gives 2.

Compare {{#time:w|20060103}} giving 2.

{{subst:DOW|2006|1|3|subst=subst:}} gives the wikitext 2.

Alternative weekday number systems are:

• 1=Monday, .. , 6=Saturday, 0=Sunday, used by variable {{CURRENTDOW}}
• 0=Monday, .. , 5=Saturday, 6=Sunday, used by en:Template:WEEKDAY and fr:Modèle:WEEKDAY

Syntax:

{{DOW|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 between 1 and 12 from january to december.
• The day is normally between 1 and 31.
