John and Doves,
 
Thanks Tony for bringing our attention to this strange event.
 
It reminded me of the River Thames event last year when a whale swam into the heart of London.

1/20/2006 London Whale
 
5/20/2007 San Francisco Whales
 
Day count - 485 days. 4+8+5 = 17.
 
Week Count - 69 weeks (rounded down)
 
Or year, 4 months
 
485 days = 69 weeks and 2 days.
 
485 = 97 x 5
 
Any other insights?
 
Blessings,
 
Phil.
