this is actually a common need nowadays - especially for those who are abroad, elderly, or simply unable to travel during the thithi. There are a few temples and mutts that offer this kind of yearly samashti shrardham or parvana shrardham service without requiring the kartha to be physically present. They’ll perform it on your behalf on the exact thithi as per the Tamil calendar, usually with sankalpam in your name and gothram.
Here are some well-known places you can check out:
1. Sringeri Sharada Peetham (Branches)
Many Sringeri branches—especially in places like Chennai (T Nagar), Bangalore, and Coimbatore—conduct yearly shrardham as a service. They maintain records and you can pay annually, and they’ll perform it without needing you there. Very reliable.
2. Sri Ramanuja Mission Trust (Chennai & Online)
They offer yearly shrardham (and monthly tharpanam too) as a registered service. You give them the details once—your name, gothram, ancestors’ details—and they take care of the rest every year. You can get the video and sankalpam copy too, if needed.
3. Kanchi Mutt – Sankara Matam
Some branches of Kanchi Mutt (especially in West Mambalam, Chennai) also help devotees with this kind of remote shrardham arrangement. Best to check directly, as not all centers do this.
4. Veda Patashalas and Agnihotra Kramas in Tamil Nadu/Kerala
There are certain Patashalas and traditional Vadhyar networks in places like Srirangam, Thanjavur, Kumbakonam, and even Palakkad, that offer Aparam and Shrardham services—especially useful for people abroad. They can handle everything end-to-end.
5. Online options like Vadhyar.com or SmartPuja
If you prefer something more tech-enabled, sites like vadhyar.com or smartpuja.com offer these services now. But you’ll have to verify authenticity and whether they really do it properly as per your sampradaya.
If you're from a specific sishya parampara (like Smartha, Vaishnavite, or Madhwa), or follow a specific mutt tradition, let me know—can help narrow it down even further.
Also, even if you're not present, try to fast or observe satvikam on that day if possible—it’s believed to strengthen the punyam of the shrardham
