Generally, unless otherwise specified, given dates that precede 15 October 1582 should be considered Julian dates. That was the date of the initial switch to the Gregorian calendar, although only Italy, Spain, Portugal and Poland made the switch on that date. I have been unable to ascertain why pre-1582 dates are not converted to their equivilents in the proleptic Gregorian calenadar, which is the name of the Gregorian calendar when it is applied to times before its own release, even though the error in the Julian calendar was widely understood and believed.
When Great Britain and all of its colonies switched to the Gregorian calendar in 1752, many people began the practice of writing "o.s." or "n.s." after dates in order to specify whether the date was old style (Julian) or new style.
Many of the founding fathers of the United States, including the first four U.S. Presidents, were born while Britain was still using the Julian calendar, but the dates that pertain to them that are recorded in our history books are "new style." In the early 1970s the US federal holiday of Washington's Birthday was moved from 22nd February to the third Monday of February. Ironically, the third Monday of February never falls on either 11th February, Washington's birthday in the Julian calendar, or 22nd February, the Gregorian equivalent.

Julius Caesar created the modern calendar in 46 BC, and it was adopted by Rome in 45 BC.His Julian Calendar of 365.25 days added winter months that were previously inconsistent, and used leap days to keep the seasons and the calendar in alignment.The current form is also called the Gregorian Calendarfor Pope Gregory XIII, who in October 1582 introduced the adjustment of the Julian calendar by skipping 10 calendar days, recognizing that the year was actually slightly shorter than 365.25 days. This calendar removes the leap days from end-of-century years (e.g. 1800, 1900) unless the first 2 digits are evenly divisible by 4.
ancient egyptians :D There has always been 365 1/4 days in a year. Thats a physical fact, that no one can alter. How it is divided up into months, is arbitary. Our modern calendar was formulated by pope Gregory and is known as the Gregorian calendar.
