Lunar calendar traces of its origin in the earlier lunar calendar, which continued to be used alongside it for religious and agricultural purposes. Present-day lunisolar calendars include the Chinese, Hindu, and Thai calendars. Synodic months are 29 or 30 days in length, making a lunar year of 12 months about 11 days shorter than a solar year. Some lunar calendars do not use intercalation, such as most Islamic calendars. For those that do, such as the Hebrew calendar, the most common form of intercalation is to add an additional month every second or third year. Some lunisolar calendars are also calibrated by
Kaula (month) Swanti. The first two days are dedicated to crows and dogs respectively. The 15th day is Lakshmi Puja when households worship the goddess of wealth in their private shrines. The day is also the last day of the lunar Nepal Era, and traditionally merchants closed their accounting books. Kaula (month) Kaulā (Nepal Bhasa: कौला) is the twelfth month in the Nepal Era calendar, the national lunar calendar of Nepal.
