तत्त्द् गतिवशन्नित्यं यथा दृक्-तुल्यतां ग्रहाः।
प्रयान्ति तत्प्रवक्ष्यामि स्फ़ुटिकरणमादरात्॥
सुर्य सिद्धान्त ॥

यस्मिन् पक्षे यत्र काले येन दृग्गणितैक्यम्।
दृश्यते तेन पक्षेण कुर्यात्तिथ्यादिनिर्णयम्॥

यात्राविवाहोत्सवजातकादौ खेटैः स्फुटैरेवफलस्फुटत्वम्।
स्यात्प्रोच्यते तेन नभश्चराणां स्फुटक्रिया दृग्गणितैक्यकृद्या॥

तिथिर्विष्णुस्तथा वारो नक्षत्रं विष्णुरेव च।
योगश्च करणं चैव सर्वं विष्णु मयं जगत्॥

Janmasthami Calculations for Seattle, WA USA for year 2009

Reference: http://www.mypanchang.com

  • Hindu day is from one sunrise to another sunrise.
  • Hindu night is from sunset to next sunrise it doesn't end at 12:00 midnight.
  • Midnight definition is middle of the night and hence exactly half of the (today's sunset - nextday's sunrise).
  • Nishitha kala is 8th muhurtha which includes midnight means 24 minutes (1 ghatika on either side of the midnight).
Festival Rule for Krishna Janmasthami Observance
  • Krishna Jansmasthami needs to be observed when Asthami prevails during nishitha kala it doesn't matter which tithi is in the morning if there is a rohini nakshatra next day and asthami doesn't prevail during midnight next day take the next day otherwise previous day. Asthami + Rohini nakshatra yoga is primary otherwise Astami prevailing during midnight is taken. If exists on both days then take the second.
Now Janmasthami Calculations
  • Sunrise on August 13th, 2009. 6:07 AM,
  • Sunset on August 12th, 20:21 PM.
  • Length of night is 9:47 minutes.
  • Midnight is never 12:00 as the sun doesn't rise at 6:00AM and sets at 6:00 PM.
  • Actual midnight is (next day sunrise - previousday sunset) / 2.
  • Midnight will be 1:14 AM on August 13 th 2009
  • Tithi saptami ends in seattle at on Aug 12, 2009 24:26 (00:26 on ...Aug 13).
  • Hence asthami prevails before midnight nishitha kala
  • Nishita kala is the eighth muhurtha.
  • Nishita kala starts on August 13th morning and 12th night from 00:40 lasts till 1:38.
  • Asthami ends on aug 13th in Seattle at 23:15 and it isn't prevailing on midnight of 13th.
  • Additionally there is no yoga of Rohini nakshatra (krishna's birth nakshatra) on August 13th
  • Hence in the pacific time zone Janmashami for fasting is on August 12th not august 13th.
  • For CST, MST, PST time zones of America, Janmasthami is on August 13th.
