For others, Hari Raya may mean just another day in captivity, with no sign yet as to when their status will be determined and their futures made clear.
Some women and children being held at a family shelter in Phang Nga province, north of Phuket, will be briefly reunited with their menfolk in the local Immigration centre.
That ''celebration'' applies to the boy born on a boat off Thailand, who will be marking his first Hari Raya, and to a girl born into captivity at Vachira Phuket Hospital in Phuket City.
Like their parents, both the young children have no citizenship and are stateless, dispossessed and unwanted.
About 2000 Rohingya are still being held in Thailand despite the passing of a six-month self-imposed deadline for the Government to make a decision on the status and futures of the detainees.
Depression and despondency continue to affect the Rohingya, especially in the Immigration centres.
Conditions for the men being held in the Immigration centres are not as comfortable as for the women and children. Eight deaths in custody in Thailand have been reported.
Rohingya being held in Isarn provinces in Thailand's north are said to be well looked after and treated ''with human dignity'' despite difficulties in translation, according to an aid agency spokesperson.

Phuketwan has not been able to determine whether celebrations - beyond family visits for a few - are being allowed today at Phuket and Phang Nga Immigration centres.
The Rohingya, fleeing ethnic cleansing in Burma's Rakine state, had hoped to reach Malaysia within days but were instead ''rescued'' from people-traffickers' camps or apprehended on boats off Thailand between January and March.
