It is understood that Eid al-Fitr and Lunar New Year will be celebrated together for three consecutive years from 2029 to 2031; the “double festivals” of these two traditional holidays are generally known as “Kongsi Raya”.
The lunar calendar differs from the Islamic calendar in that the Islamic calendar is based on the number of days in the lunar month, and there are 12 months in a year, with odd-numbered months such as January, March, May, July and September being the major months (30 days per month), and even-numbered months having 29 days per month, averaging 354 days per year.
As for the lunar calendar, there are 12 or 13 months in a year, and the number of days in each month is 29 or 30 days, depending on the orbital cycle of the moon around the earth.
It is worth mentioning that “Kongsi Raya” was celebrated in 1964, 1965, 1966, 1996, 1997 and 1998, where Muslims and Chinese compatriots celebrated Eid al-Fitr and Lunar New Year at same days for three consecutive years from 1996 to 1998.
