There are 365 days in a year or 366 days in a leap year. Usually any year divisible by 4 is a leap year, the exception is that centenary years are not leap years unless divisible by 400. (If February has 29 days then it is a leap year, with 366 days).
you dont have to you adding or counting but you just have to remember that eery thing is in relavance to something.
Sosigenes created the calendar to follow the equinoxes. He used the Julian Calendar that was created by Julius Caesar in 46 B.C. To do this he calculated that 23 days be added after February 23rd, two months be added between the end of November and the beginning of December. Thus, adding 67 days to the "then" calendar.
Count the Days was created in 1994.
30 calendar days is 30 days including weekdays, weekends and holidays.
The Julian calendar is 13 days behind the Gregorian calendar from March 1900 until March 2100.

Julius Caesar is credited with changing the Roman calendar from 355 days to 365 days and for adding leap year days every few years (and for changing the name of Quintilis to July in honor of himself).
including 1535 and 2012, and not counting the ten days that were removed from 1582 when the initial switch to the Gregorian calendar happened, 174577
Counting from December 1, 2011, adding 90 days to this date gives February 29, 2012.
19 more days without counting the weekend
The Romans "invented" the calendar as we know it. Without researching it, the first calendar with leap days, with the 12 months as we know the calendar, was the Julian calendar named after Julius Caesar. It had an error of about 3 days in 400 years. This calendar was replaced by the much more accurate Gregorian calendar by decree of Pope Gregory in the late 1600's in the Catholic countries and accepted by most Protestant and other countries in the 1700's. There was an adjustment of 12 or 13 days in the calendar at that time. The Gregorian calendar is the calendar we use today. Prior to the Julian calendar, days were added as needed in all calendars including the one which began in March and had only 10 months ! This is why the 12th month, December, comes from the Latin word for ten. The Mayan and Chinese calendars, among others, were known for their accuracy and would have had to add days also.

No. The date is based on an ancient calendar and misunderstood by many people. It is just a calendar, one of a great many, a way of counting days. Nothing more or less than that.
