was
a difference of ten days between the current calendar year and the seasonal
average year up to 4th October 1582 A.D. Therefore, the average year
of the current international calendar up to 1582 A.D. lagged behind the
seasonal average year and all the weather begins to occur 10 days in advance.
When this fact came to the knowledge of the Pope Gregory XIII, he ordered to
replace the date of 4th October 1582 with the date of 14th
October 1582 so that the months would come and go according to the seasons. And
he set new rules to reduce the number of leap years to prevent this error for
the future also. According to these rules every 100th year not to be
taken as leap year but every 400th year to be taken as leap year
also. But despite that, it will still have one day error in year 3000 C.E. The
coming of the seasons of the international calendar months is nothing short of
a blessing to people around the world. Because people know in advance what
month the weather will be like, they keep it in mind as they plan their next
event. To protect our children from extreme heat in our country, Pakistan has
holidays every three months of June, July and August. Similarly, farmers around
the world plan in advance to sow, harvest and handle their crops in the name of
the months of the international calendar. Because of the abundance of weather
forecasts, people around the world are not tired of using it.
