Dates et lieu du festival du Phulech en Inde

Bonjour à tous,
j'aimerai connaitre les dates et lieux exacts du festival des fleurs (phulech) qui à lieu tous les ans en septembre dans l'état de l'Himachal Pradesh.
Merci

je n'ai pas trouvé d'infos précises.
juste ceci :
SEPTEMBER:As the rains end, autumn sends fiery colours racing through the hills. In Kinnaur, the festival of flowers, 'Fullaich' (Phulech) opens a window to its remarkable people and their beautiful countryside. Villagers scout the hillsides for flowers which are collected in the village square. These are then offered to the local deity. Then comes a spate of revelry - singing, dancing and feasting. Kalpa has some of the most vibrant celebrations and every twelve years, there is a special festival. Also in September, at the village of Chhatrari, near Chamba - and centered around the exquisite temple of Shakti Devi - a fair is held and masked dances are performed.Source : site web de l'himachal tourism
