Plain dates

Dates with no calendar are in the Gregorian calendar if 1584-10-15 or later and in the Julian calendar if 1584-10-04 or earlier. (Dates in between are errors.)

• [[Date: 15 November 2003]]
• [[Date: 15 Nov 2003]]
• [[Date: 1st January 1543]]
• [[Date: October 4, 1212]]
• [[Date: 2004-07-15]]
• [[Date: May 1066]]
• [[Date: 2004]]

Dates with calendar

Put the calendar in parentheses following the date.

• [[Date: 16 January 1672 (Old Style)]]
• [[Date: June 30, 1776 (New Style)]]
• [[Date: 1912-05-12 (Julian)]]
• [[Date: 1666-04-02 (Gregorian)]]

Dates always assume the 1 January beginning of the year.

Non-Western calendars could be supported.

• [[Date: 7 Tishri 5772 (Hebrew)]]
• [[Date: 7 Muharram 1425 (AH)]]

Ranges of dates

Separate the dates at the start and end of the range with a slash. The range is inclusive of both endpoints. If only one of the dates has a calendar, the calendar is assumed for the other.

• [[Date: 1584-10-04 (Julian) / 1584-10-15 (Gregorian)]]
• [[Date: 12 May 2003 / 12 June 2003]]
• [[Date: May 2004 / Jun 2004]]
• [[Date: 1941/1945]]

Imprecise dates

Put "c." or "circa" before a date to make it approximate.

• [[Date: c. 1065 / 1088]]
• [[Date: c. 2100 BC / c. 2050 BC]]
