The Gregorian calendar is the standard calendar of the "western" world. It was introduced in 1582 as a reform of the Julian calendar, which is almost identical but has 7.5 more leap year days per millennium than the Gregorian calendar, making it about 25 times less accurate.
Muslims needed an accurate calendar primarily to determine the correct dates for religious observances and rituals, such as Ramadan, Hajj, and the timing of daily prayers. The Islamic calendar is lunar, consisting of 12 months, which is essential for aligning these important events with the phases of the moon. Accurate timekeeping ensures that Muslims fulfill their religious duties at the appropriate times throughout the year.

The most accurate calendar system used globally is the Gregorian calendar, which is the most widely used calendar system in the world today. It was introduced by Pope Gregory XIII in 1582 to correct inaccuracies in the previous Julian calendar. The Gregorian calendar is based on the solar year and is more accurate in aligning with the Earth's orbit around the sun.

Probably shortly after the development of the calendar.
The Maya had two main calendars: the Tzolk'in, a 260-day sacred calendar, and the Haab', a 365-day solar calendar. By combining these calendars in a cycle known as the Calendar Round, the Maya were able to track time accurately and synchronize different aspects of their society. Their calendars were remarkably accurate for their time, with the Haab' calendar being only around 17 seconds off from the actual solar year.
