Buddhist calendar
Vietnamese Buddhists keep their festivals by the lunar calendar. Two days recur every month: the first day of the lunar month and the full-moon day (the 15th). Many people eat vegetarian food or visit a temple on these days, as they are able.
The dates below are computed by a program when this page is built, using the Vietnamese lunar calendar (UTC+7). It can differ by a day from the Chinese lunar calendar, because the two countries use different time zones. Temples may also announce slightly different dates, so check the notice of the temple you plan to visit.
