Sri Vaishnavam 
Adiyen Ramanujar Daasan,
Ananthakoti dandam samarpithu seyyum vignyapanam enna vendral, We are very much eager in registering vivaham site since it is already late for my brother to get marriage. Kindly let us know how to register or how to login for vivaham.
Adiyen Ramanuja Daasan,
Dear Bhagavathaas,
Please let me know if there is any book (in English) which provides list of festivals to be celebrated by Sri vaishnavas and a detailed method of celebration of each festival. It is because we have observed that there is no uniformity among Sri vaishnavites , inherent differences appear in all our AAchaara / Vichaarangal.
Adien daasan,
Channakeshava Nambi
Swamin,
The festivals that are common to both kalais are mArgazhi mAsam, panguni utthiram, Sri Rama Navami, EmperumAnAr thirunakshatram, NammazhwAr Thirunakshatram, Avani avittam, thiruvAdipUram, Sri Krishna Jayanthi, naraka chathurdasi thirukArthikai and vijaya dasamI. The rituals that are performed at home are mArgazhi, Sri Krishna Jayanthi, naraka chathurdasi, kArthikai and vijaya dasami. The rest are generally celebrated in the temples. The rituals vary depending on level of orthodoxy and geographic limitations.
Vadakalais will celebrate Swami Desikan thirunakshatram in kOyil; Tenkalais will celebrate Manavalamamunigal thirunakshatram, also in the kOyil.
