It's not so much the calendar as time:

They rounded up the lunar month to 30 days making the year 360 days, or 6 x 60 days. This 360 was used to divide up the sky and is used today in dividing up a circle in a plane - in 360°.

Where we see Sumerian influence in in time which is measured using sexagesimal (base 60) numbers - there are 60 seconds in 1 minute, 60 minutes in 1 hour.

When writing numbers in different bases, those less than 10 use a subset of the digits 0-9, those over 10 (eg 16 - hexadecimal) use the letters of the alphabet (eg hexadecimal uses 0-9 and a-f). As there are only 26 letters, this limits the base to 10+26 = 36. It could be extended by prescribing use of capitals and lower case letters for higher bases, but instead decimals are used with a symbol to separate the different digits.

For base 60, we use decimal numbers separated by a colon for time, and digits followed by ° (degrees) ' (minutes) " (seconds) for angles.

Using the sexagesimal place value system, each column is 60 times the value of the column to its right, giving ... : 3600 : 60 : 1 as the place column values.

Using the 24 hour clock any time (to the nearest second) is actually the sexagesimal representation of the number of seconds since midnight: H:M:S, for example, 1 minute past midnight = 0:1:0 = 0 × 3600 + 1 × 60 + 0 = 60 seconds past midnight (which makes sense a 1 minute = 60 seconds). Similarly, 15 seconds past 20 minutes past 5 in the afternoon is 17:20:15 = 17 × 3600 + 20 × 60 + 15 = 62415 seconds since midnight.

Was the 365-day calendar achievements of the Sumerian?

No, astronomy didn't start until the time of Babylon and when the Babylonians did invent the calender, there was only 354 days in the calender, so every few years, they had to add another month.

What is the sumerian government structure?

Sumerian GovernmentThe Sumerian government was principally a bureaucracy. The monarchy effectively held power over great areas of land and diverse peoples by having a large and efficient "middle management." This middle management, which consisted largely of priests, bore all the responsibility of surveying and distributing land as well as distributing crops. There was never a Sumerian empire and power constantly shifted between cities. There were many leaders like Hammurabi who made the code of laws very sucessful.

What is the difference between Gregorian calendar and Roman calendar?

The difference is the accuracy of mathematical computation of the length of the day, in essence. The Roman calendar was fairly accurate (considering the computation tools of the time, quite accurate), but over a period of many years, it was off by a period of (then) ten days. The Gregorian calendar proposal used more precise mathematics, and deduced that the calendar had lost ten days since the calendar of Rome was established. The calendar was jumped forward ten days (it's a long story). The current (Gregorian) calendar is accurate to about one day every several thousand years.
