Up there���� you have over 20 different calendars in use or once in use in the world. I decided to dig into this to let you know that the Gregorian Calendar in use in most part of the world, Nigeria inclusive, is not the only regulator of man and his activities on earth. In other words, while we're in a mad rush to make it before December 31st, 2020, some persons in another part of the world are less concerned about our death-race hustling. This is because these Calendars do not begin and end the same time.
I want you to take it easy with yourself. Man invented calendar and over the years adjusted it, abandoned it or reinvented it to suit his purpose. You must know January 1st is not the beginning of the year for everyone on earth. Likewise, December 31st isn't the end of the year for everybody on earth. Instead of killing yourself for not achieving your goals for the year, try to draw up a broad plan for yourself and pursue it throughout the days of your sojourn on earth.
You're created for great things. Pursue these things.

Wishing you the best all the time.

Is it now clear to you why the world is confuse?

Well, what ever your plans are, work it out considering the calendar you find yourself where it is used.

Be it Gregorian, Jewish and so on. The most important thing is, Just plan well for yourself in any calendar you find yourself.
