Leap days are added into the calendar once every four years on years that are divisable by four except when they occur on the turn of a century [ie years that are divisable by 100]. This latter condition is waved in the case of years that are divisable by 400, thus the year 2000 was a leap year, where 2100 will not be [because while it is divisable by 4 and 100 it is not divisable by 400]. This system will keep the calendar in balance for many years to come, running into the thousands I believe - but still other adjustments will need to be made.
Can anyone tell me what the next 'extraordinary' leap day will need to be over and above the rules outlined above; has it even been worked out. OR ... are the adjustments needed so small that they can be acieved using the addition/subtraction of 'leap seconds' on the international clock at the end/start of years?
[As an aside does anyone else agree that the co-opting of the year 2000 just the satisfy the 'aesthetics' of the situation, in order to celebrate the millenium was a mistake. Forgeting the birth of Christ aspect [and the fact that he bollocksed up the year calculation], When Dionysius Exiguus published De Temporum Ratione in 725 ad {on which the whole thing was based in respect of fixing the year date to the birth of Christ}, the concept of zero as a number was not as yet understood. Thus he began his calculations from 'the year 1' rather than the year dot. Thus the Millenium Cellebrations, in order to celebrate [what..... 1275 years of using the same calander]....er.... the millenium should have been held on 00.00 on the 1st Jan 2001. It's a fact; Am I right or am I right, I ask you!
