Why is it 360 degrees but 365 days?
The 365 days is the division of a year which is basically a time. Now in similar way 360 degrees is the division of circle in terms of angle. Therefore both the things are different and they are not equivalent.
Why are there 365 degrees in a circle?
You might conclude that the Sun moves about 1/360 of the way along this circle every day. The Earth takes one year to orbit the Sun. And a year is just a little more than 365 days. Each of these parts was dubbed 1 degree, thus giving us the idea that a circle contains 360 degrees.
Are there 360 or 365 days in a year?
All months are considered to last 30 days and hence a full year has 360 days, but another source says that February has its actual number of days. US/NASD method (30US/360) All months are considered to last 30 days and hence a full year has 360 days.
How did they come up with 360 degrees in a circle?
The Mesopotamians passed their base-60 numerical system to the ancient Egyptians, who used it to divide a circle into 360 degrees. Therefore, six triangular slices of 60 degrees each made for a sensible 360-degree dissection of a circle.
Who uses 360 days in a year?
To solve this problem the Egyptians invented a schematized civil year of 365 days divided into three seasons, each of which consisted of four months of 30 days each. To complete the year, five intercalary days were added at its end, so that the 12 months were equal to 360 days plus five extra days.
How many days are in Babylonian year?
354 days
Babylonian calendar, chronological system used in ancient Mesopotamia, based on a year of 12 synodic months—i.e., 12 complete cycles of phases of the Moon. This lunar year of about 354 days was more or less reconciled with the solar year, or year of the seasons, by the occasional intercalation of an extra month.
Why is the earth divided into 360 degrees?
George Cantor 1 suggested that its origin can be traced to the fact that the early Babylo- nians reckoned the year to consist of 360 days during which the sum made a complete circle round the earth. This led to be division of the circle into 360 degrees, each degree being the distance traversed by the sun in one day.
Who developed the calendar for 360 days?
the Egyptians

Was there always 365 days in a year?
Background: The true length of a year on Earth is 365.2422 days, or about 365.25 days. We keep our calendar in sync with the seasons by having most years 365 days long but making just under 1/4 of all years 366-day “leap” years. History: – The ancient Egyptians and others used a year with exactly 365 days.
