The Romans had three calendars over the 1,200 years of their history. Only the first one, the Romulean calendar created by Romulus, Rome's first king, had 10 months and this lasted only for about 40 years. The second king of Rome, Numa Pompilius, reformed the calendar and created one with 12 months (the calendar of Numa). The Julian calendar, created by Julius Caesar, also had 12 months. Caesar also switched from a lunar to a solar calendar.

The Muslim calendar, or Hijri calendar, is a lunar calendar consisting of 12 months and about 354 days, making it shorter than the solar year. This causes Islamic months to shift approximately 10-12 days earlier each year in relation to the Gregorian calendar. In contrast, the Chinese calendar is a lunisolar calendar, which incorporates both lunar months and solar years, resulting in a year that typically has 12 months but adds a 13th month periodically to align with the solar year. Consequently, the Chinese calendar is more aligned with the seasons compared to the purely lunar Muslim calendar.
Why are the Muslim different and Chinese calendars different?
The Muslim and Chinese calendars differ primarily due to their foundational systems; the Muslim calendar is a lunar calendar based on the cycles of the moon, while the Chinese calendar is a lunisolar calendar that incorporates both lunar and solar elements. The Islamic calendar has 12 months totaling about 354 or 355 days, leading to a shift of about 10 to 12 days earlier each year. In contrast, the Chinese calendar aligns its months with the moon phases and includes intercalary months to synchronize with the solar year, resulting in a cycle of 12 or 13 months that can total 353-385 days. These differences reflect the cultural and religious contexts in which each calendar developed.

Why does each month have a different number of days?
The varying number of days in each month is a result of the ancient Roman calendar's evolution. Originally, the calendar had ten months, totaling 304 days, with a winter period left unassigned. To align the calendar with the lunar year and agricultural cycles, January and February were added, leading to the current structure of 12 months, with adjustments made to account for the solar year, resulting in the differing lengths of each month. The system was further refined during the Julian calendar reform in 45 BCE, establishing the familiar pattern we use today.
