The second month in the Georgian and Julian calendars, which has 28 days or 29 days on a leap year, and is the shortest of the 12 months. Use this tag when the month's full name appears in the post, whether by itself, as part of a celebration or birthday, or on a calendar. In Japan, it is written as 二月 (nigatsu), although 2月 is acceptable and can be tagged as February.
