calendar month

means a period beginning at the start of any day of one of the 12 months of the year (a named month) and ending —

(a) at the end of the day before the corresponding day of the next named month; or
(b) if there is no corresponding day — at the end of the last day of next named month.

Examples

1 The period beginning at the start of 5 July 2009 and ending at midnight on 4 August 2009 is a calendar month.
2 The period beginning at the start of 30 January 2009 and ending at midnight on 28 February 2009 is a calendar month.

The calendar month ends on the last day of February because in that year February does not have a day corresponding to 29 January (because 2009 is not a leap year). If the period began at the start of 30 January 2012 (ie a leap year), the calendar month would end on 29 February 2012.
