The calendar now almost universally in use is the Gregorian calendar introduced in 1582
One was a lunar calendar based on the phases of the moon. Priests used this calendar to determine religious days and lucky days. The other was a solar calendar,based on the movement of the sun. It's similar to the calendar we use today
Yes, the Mayans developed a sophisticated lunar calendar that tracked the phases of the moon. Their calendar system, known as the Tzolk'in, consisted of 260 days based on the cycles of the moon and was separate from their solar calendar.
It, too, has 365 days and is based on seasons.
The classical Roman calendar was originally lunar, but later developed into a similar system to the modern one (in fact it was a precursor to the current Julian calendar) using months of either 30 or 31 days.
Their counting system was based on 20, to the best of my knowledge. Also they saw the year as 360 days. This is a multiple of 20. That may explain why.

No, the Jewish year has 365.25 days, just like the Gregorian, but the calendar is calculated differently. The Gregorian calendar is Solar, meaning it's based on the Sun; the Jewish calendar is Lunisolar, meaning its based on the Moon, but periodically corrected to match the Sun. By contrast, the Islamic calendar is Lunar and has only 354 days in a year.
28 days. That is how many days there are in the Islamic calendar, which is based on the phases of the moon.
It doesn't. It has 354 days because the months are lunar. But an extra leap month is sometimes added.
The Hebrew calendar is a lunisolar calendar. The months are 28-29 days based on the lunar cycle, but the leap year system is based on the solar cycle. The lunar year is 354 days, but every few years, a leap month is added to keep the months in the same seasons.
Ramadan follows the lunar calendar and it moves up 13 days each year based on the moon's position.
The Roman Calendar has 10 months in its system. Among these ten months, there were 304 days. This has been expanded on to 12 months and 365 days, which is still used today.
