It is only more than just 90 days from now until we finally complete a year. New yearâ€™s resolutions are coming and the holidays magic is brimming but what exactly do we mean when we say we have completed another year around the sun?

The question of how many days in a year may be a bit clichÃ© but we are under-appreciating it. There are various calendar years so when someone asks you how many days in a year, you should know that it is not automatically 365. But how is that possible?

How many days in a year exactly?

Well, we go by the common year or the modern Gregorian calendar as they say. So by this concept we know that there are exactly 365 days in a year. But there are also times when the answer could be relative. Say for example, in a leap year, there will be 366 and for lunar year, it would be 354. So honestly, being exact on the number of days in a year means we also have to exact in what calendar year we are referring to.Â

1 common year = 365 days

1 leap year = 366 days

1 lunar year = 354

How many days in a leap year

According to Entity Mag, one leap year would have 366 days instead of the usual 365. The additional day is what we know as February 29th which only exists once in every four years and it traces back its origin to Julius Caesar who had this fetish of making everything exact but turned out that his measurement of the movement of the earth around the sun was inexact too, hence, the leap year.Â

1 leap year = 366 days

How many days in a Gregorian year?

There are other calendar years and for each of them, the number of days in a year might have slight differences. For example, the Gregorian calendar was the basis of the common calendar, so basically, they count the number of days in a year similarly which is at 365.

1 Gregorian year = 365 days

How many days in a Lunar year?

How many days in a Julian year?

1 Julian year = 365.25 days
