Template:Orddate2m

This template takes a positive orddate from 1 March and returns the associated month number within the Gregorian calendar, extrapolated to month 14. Also negative orddates for february give the correct month.

• "{{Orddate2m|-27}}" gives "2" [1]
• "{{Orddate2m|0}}" gives "2" [2]
• "{{Orddate2m|1}}" gives "3" [3]
• "{{Orddate2m|31}}" gives "3" [4]
• "{{Orddate2m|32}}" gives "4" [5]
• "{{Orddate2m|61}}" gives "4" [6]
• "{{Orddate2m|62}}" gives "5" [7]
• "{{Orddate2m|92}}" gives "5" [8]
• "{{Orddate2m|93}}" gives "6" [9]
• "{{Orddate2m|122}}" gives "6" [10]
• "{{Orddate2m|123}}" gives "7" [11]
• "{{Orddate2m|153}}" gives "7" [12]
• "{{Orddate2m|154}}" gives "8" [13]
• "{{Orddate2m|365}}" gives "14" [14]

Wrong value (in common year) because out of range:

• "{{Orddate2m|-28}}" gives "2" [15]
• "{{Orddate2m|366}}" gives "14" [16]

This template uses a basic formula, based on the 5-month cycle 31-30-31-30-31, repeating itself some more than twice: Mar-Jul, Aug-Dec, Jan.
