Planning a surprise party for a friend's birthday, but you're unsure about the exact date. With our date calculator, precisely determine the exact date by adding the remaining days to the current date. 

A Brief History of The Gregorian Calendar:

The Gregorian calendar introduced a leap day in February during leap years, with standard years having 365 days. According to it, The months of April, June, September, and November have 30 days, while the rest have 31 days except for February. February has 28 days in a standard year and 29 days in a leap year.

Derived from the Julian calendar, The Roman calendar, based on lunar observations, led to inaccuracies in tracking the solar year. Julius Caesar reformed it in 46 BC, introducing a 365-day year and a leap day every four years. Pope Gregory XIII made further adjustments by skipping 10 days in 1582 and changing leap year rules. Even though it took time, but now the Gregorian calendar is most famous and used worldwide.
