ANSWER:
The Gregorian calendar the most used in the world and named after Pope Gregory XIII, who had created the calendar in the year October 1582.
EXPLANATION:
The calendar was created as a modification to the earlier used Julian calendar, curtailing the avg. year by 0.0075 days so as to stop the calendar from drifting pertaining to the equinoxes. The Gregorian calendar's precursor, the Julian calendar, was switched since it was too erroneous. It did not correctly reveal the real time it takes for the Earth to revolve around the Sun, termed as a tropical year.
The formula of Julian calendar utilised to calculate the leap years created a leap year every 4 yrs. This was too frequently, and ultimately, the Julian calendar was many days out of sync with the static dates for astronomical events such as solstices and equinoxes. The creation of the Gregorian calendar enabled for the re-alignment with events such as the winter solstice and vernal equinox.
