What is the difference between the lunar and solar calendar ?
The solar calendar has 365 days and is based on the amount of time it takes for the Earth to complete one orbit around the Sun. Beacause it’s based on the orbital period of the Earth, the seasons occur around the same time each year. The lunar calendar has 354 days in the year and it’s based on the phases of the moon and tides. For this reason, the phases of the moon occurs around the same time each month.
