My teacher told us yesterday that Feb 29 is a special day for woman in England. That’s a traditional day in which a woman can ask her favourite man to marry her. We have the Feb 29 this year, that means we’re in the leap year.

A leap year (or intercalary year) is a year containing one or more extra days (or, in the case of lunisolar calendars, an extra month) that occurs only every four years, in years evenly divisible by 4(with the exception of century years not divisible by 400, such as 1900) for the Gregorian calendar, in order to keep the calendar year synchronised with the astronomical or seasonal year. For example, in the Gregorian calendar, February would have 29 days in a leap year instead of the usual 28. Because seasons and astronomical events do not repeat at an exact number of full days, a calendar which had the same number of days in each year would, over time, drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year which is not a leap year is called a common year.

I saw this advertisment of the Republic of Singapore Navy on my bus to Britisch Council this morning. It’s quite interesting and creative.
