Although the moon takes 27.3 days to orbit the earth it takes 29.5 days to complete its phases (because the earth is moving too). This makes it a bit tricky to nail down exactly on which date a full moon occurs, even in the lunar calendar. To cope with this some lunar months are 29 days and some are 30 days. In the wash-up the full moon usually occurs on the 15th or 16th day of each lunar month but not always.
In addition, some years have thirteen full moon festivals, not twelve, if the first of these falls on the first day of the month. In 2026 for example, there is a full moon lantern festival in Hoi An on 1 April and 30 April.
For the Hoi An Full Moon Lantern Festival the organizers have taken some of the complications away and the celebration occurs on the 14th day of the lunar calendar, regardless of when the full moon actually occurs.
Thus, in the Gregorian Calendar, the festival occurs on the following dates:

Hi Harshit,
We have a post dedicated to the Full Moon Lantern Festival Calendar – https://hoiannow.com/hoi-an-guide/festivals-in-vietnam/full-moon-lantern-festival-calendar/ – for all those planning visits.
The date in January 2023 is the 5th and the date in February 2023 is the 4th. Everything takes place in Hoi An Old Town by the river’s edge. Follow Bach Dang Street towards the Lantern Bridge (that connects Hoi An Old Town to An Hoi Islet) and you can’t go wrong.
Hello,
i´m planning to visit Hoi An on December 2022. and i would like to see the Lantern Festival . But i have a question, Is on 07 or 08Th DEC.
I saw another websites that the date is 08DEC, now, im very confused if is on 07TH or 08TH DEC. Where can i check this information?
Thank you so much.
Hi Marcos, The Full Moon Lantern Festival is always celebrated on the 14th day of the lunar calendar even though the full moon may be on the 14th, 15th or 16th. It’s complicated as we say in this post. Happily, in December 2022 the 7th of December is both the 14th day of the Lunar Calendar and the full moon. You can check this using the following independent sources: https://www.hko.gov.hk/en/gts/time/calendar/pdf/files/2022e.pdf and https://www.almanac.com/full-moon-december. Thus, 7th of December 2022 is correct.
All the information about the Full Moon Lantern Festival can be seen here: https://hoiannow.com/hoi-an-guide/festivals-in-vietnam/hoi-an-lantern-festival/ … It is not yearly, it is monthly. If you still have more questions please let us know.
Hello! Thank you so much for putting this info together. I am basing my Vietnam itinerary around making it in time for the full moon festival in Hoi An in May (in 2 weeks!). I will be there on 2nd and 3rd May nights, based on this calendar and some others I found online, however on some websites I saw it’s on 5th May! I really don’t want to miss it – please can you advise, are these dates fixed? Can I definitely expect it to be on 2nd or 3rd May or could it possibly end up being on the 5th?
Thank you in advance.
Hi Nilofar, Yes it can be confusing. It is true that the full moon actually falls on 5 May in 2023. But the Full Moon Lantern festival in Hoi An is ALWAYS on the 14th day of the lunar cycle whether or not the full moon falls on that day (the full moon is actually most often on the 15th and 16th days of the cycle). In May 2023 the 14th day of the lunar cycle falls on 3 May. On our post https://hoiannow.com/hoi-an-guide/festivals-in-vietnam/hoi-an-lantern-festival/ we have a full explanation as follows:
Curiously, the Hoi An Lantern Festival is not always celebrated on the night of the full moon. To keep things simple it is always celebrated on the 14th day of the lunar calendar, which is usually just before the full moon.
The exact date of the full moon changes because some lunar months are 29 days while others are 30 days. However, organizers in Hoi An have created uniformity for everyone by holding the festival on the 14th day of the lunar calendar each month, regardless of the full moon’s precise date.
So, the bottom line is: in May 2023 the Full Moon Festival will be held on 3 May.
Hi Stuart,
Thank you so much for your prompt reply, this has put my mind at ease! All the information makes much more sense now.
Super excited to experience this rare opportunity!
Thank you once again,
Nilofar
The above calendar says that it’ll be held on the 2nd of May? So is it on the 2nd or 3rd?
You are right. Well spotted. 3 May is the 14th day of the lunar cycle. We have made the correction.
Hi Stuart,
I have noticed in some websites its its 26th December 2023 and in some i have noticed 27th December 2023. which date is it exactly the lantern festival in the month of December 2023 . appreciate your help. thanks
The Hoi An Lantern Festival in December will be held on the 26th of December. The actual full moon is on the 27th of December, however. The lunar calendar is complicated but as we say in the post above: ‘For the Hoi An Full Moon Lantern Festival the organizers have taken some of the complications away and the celebration occurs on the 14th day of the lunar calendar, regardless of when the full moon actually occurs.’
Hello
Where can I buy the tickets for the full moon latern festival?
Thanks!
No special tickets are necessary to attend this festival. Just head towards the center of the Hoi An Old Town.
Looking at Sept or Oct keen to do full moon festival would it be better in sept less rain ?
What happens if it’s flooding does it still go ahead ?
September has less rain than October and it rarely floods in September. If the Old Town is in full flood it is not possible for the festival to occur but this is rare.
