Problem Description
Most of us have a calendar on which we scribble details of important events in our lives---visits to the dentist, the Regent 24 hour book sale, Programming Contests and so on. However there are also the fixed dates: partner's birthdays, wedding anniversaries and the like; and we also need to keep track of these. Typically we need to be reminded of when these important dates are approaching---the more important the event, the further in advance we wish to have our memories jogged.
Write a program that will provide such a service. The input will specify the year for which the calendar is relevant (in the range 1901 to 1999). Bear in mind that, within the range specified, all years that are divisible by 4 are leap years and hence have an extra day (February 29th) added. The output will specify ``today's'' date, a list of forthcoming events and an indication of their relative importance.
