अद्य अमेरिकादेशे श्रीजयन्ती आचर्यते श्रीसन्निधिशिष्यैः। सामान्यतया अस्मिन् दिने पद्यं किञ्चित् स्वीकृत्योल्लिख्यते कृष्णविषये परं साम्प्रतं न पद्योल्लेखनम्। अस्मिन् वर्षे विचित्रजयन्त्याचरणं वर्तते यस्मिन् विषये प्रतिपादयामि। भारते तु श्रीजयन्ती September-15तमे दिनाङ्के परमत्र August-17th एव। अत्रापि अन्ये श्रीवैश्णवाः सेप्टम्बर-मासे आचरन्ति। किमिदं कृष्णलीलेति कुतुहलो जातोतः आह्निकग्रन्थं स्वीकृत्य आलोडितवती। तदेवात्र प्रतिपाद्यते।

Note: This guideline applies only to Śrī Ahobila Maṭham śiṣyas, since I follow only that sampradāya and the Āhnika-grantha was authored by Śrīmad Azhagiya Siṅgar, the 45th Jeer of Śrī Ahobila Maṭham.

Rule for Celebrating Sri Jayanthi

Primary Rule: Celebration should be on Siṃha (Āvani) Māsa, Kṛṣṇa Pakṣa Aṣṭamī, with Rohiṇī Nakṣatra.

⚠️ Condition: There must be no overlap of Saptamī or Kṛttikā Nakṣatra, even for a vināḍi. This is termed śuddhāṣṭamī-sahita-rohiṇī.(शुद्धाष्टमीसहितरोहिणी)

If this exact combination is not available, then:

1. Check for śuddha-rohiṇī + Navamī (शुद्धरोहिणी + नवमी) — which occurs today, and hence we celebrate Śrī Jayanthi today in the USA.✅
2. If that is also not available, then check for Mṛgaśīrṣa + Navamī/Daśamī. (मृगशीर्षः + नवमी/दशमी)

Addressing the Pūrva-pakṣa–

Some may argue that since Rohiṇī Nakṣatra also occurs on Sept 13th, and as per the rule, when a Nakṣatra occurs twice in a month the festival should be observed on its second occurrence, the celebration ought to be on Sept 13th.
This is a valid point, so let us examine carefully:

• Sept 13th: Saptamī + Rohiṇī.
  As per the primary rule, there must not be Saptamī even for a moment. Hence, this day is ruled out — Śrī Jayanthi cannot be ❌ celebrated.
• Sept 14th: Aṣṭamī + Mṛgaśīrṣa.
  Rule 3 allows Mṛgaśīrṣa with Navamī or Daśamī, not with Aṣṭamī. Hence, this day is also ruled out.❌

Conclusion–

Therefore, in line with the instructions of HH in the Āhnikam:

• No śuddha Rohiṇī with Aṣṭamī this month.
• Śuddha Rohiṇī + Navamī occurs today.

👉 Therefore, Śrī Jayanthi is to be celebrated today (in the USA).

(I’m honestly so impressed with the SAM USA Calendar Team—they nailed the calculations to the very last detail. Hats off to you all!)

FYI – In Bharatham, it is still Adi so they can’t celebrate today!

Note – I also had a kutūhala (doubt/curiosity) since Śrī Sannidhi Śiṣyas have a feast on Jayanthi, whereas others observe upavāsa. I found the answer in Āhnika!

अयं भगवतः जन्मोत्सवः तर्हि उत्साहेनाचरणीय एव।

श्रीजयन्ती-शुभाशयाः सर्वेभ्यः। श्रीकृष्णः सर्वदा अस्मान् पातु। जय श्रीकृष्णः।
