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.
