How many days are there in a year? What is a tropical year? What makes a year a lunar year? What defines the length of a day? If these questions have found a permanent residence in your brain, then these answers will help you out.
The Julian calendar was introduced by Julius Caeser in 46 B.C. The Julian year had 365.25 days. Since the calendar was not so precise, the Romans came up with another calendar. Much aware of the fact that the Earth took 365.25 days to orbit the sun, they still decided to make a calendar with 355 days. Although the intercalations were supposedly systematic, the priests often abused it. They demanded for additions or omission of months as per their convenience. These confusions led to the year being named as the “the year of confusion.”

Scientifically speaking, the earth takes about 365.2422 days to complete its orbit around the sun, which is 365 days, 5 hours, 48 minutes, and 46 seconds. But the Earth doesn’t spin like a globe but like a top. This means that the earth’s position keeps on shifting and thus the movement of the equinox. This makes a tropic year end almost about 20 minutes before the Earth finishes its orbit.
The Gregorian calendar that has been accepted internationally was named after Pope Gregory XIII, who led to its introduction in the year 1582. It is believed that the calendar served as a refinement to the Julian calendar. According to this calendar, there are 365 days in a year with 0.25 day (6 hours per day) left every year. Adding it up, every year that is divisible by four has an extra day (i.e. 24 hours) which falls on the 29th February, making it a leap year.

The story doesn’t end here. The Earth’s orbit is not the same every year. The forthcoming presence of the massive Jupiter, the ellipse around which the Earth defines its movement around the sun becomes misleading. These measurements might lead you astray in case you were considering calculating the time spans.
The reforms brought in with the creation of the Gregorian calendar gave a solution to the problem of length differences. It occurred due to change in the mean length of the calendar year i.e. from 365.25 days (365 days 6 hours) to 365.2425 days (365 days 5 hours 49 minutes 12 seconds) which is a reduction of 10 minutes 48 seconds per year.
Now that you are aware of the number of days that fall in a year and the science behind it, move beyond the issue, rather try to make each day worth living. Set your goals of spending your time in the best possible manner; be it with your family, friends or for any recreational activity that makes you happy.
