The 365 day solar calendars are much more practical and accurate than 29.5 day moon calendars. As the lunar calendar is governed by the cycle of 29 and a half days of the moon, in ancient times it was much used for the resemblance to the menstrual period of the woman, and with the pregnancy time of 10 lunar months. However, it can't be compared to the accuracy of the solar calendar, which also brings together the four seasons of the year, and it was the most popular in the West since lunar cycles are inaccurates for modern requirements. This because each month would have half a day that would be lost or added to next month, but finally at the end of the year, the lunar cycles would not fit well with the human lunar calendar.
