"17 and 18 June 2009 (on Gregorian and Jewish calendars) combined with prime numbers yield 666 twice"

 
Using inclusive and non-inclusive day counting: 17 June and 18 June of 2009 are 999 days from Rosh Hashanah 5767 (23 September 2006).
 
   999 is an inverted 666.
 
17 June and 18 June are the 168th and 169th days of 2009. They are the 261st and 262nd days of 5769.
 
   17 June >>> The difference between the 261st and 168th prime numbers is 666.
   18 June >>> The difference between the 262nd and 169th prime numbers is also 666.
 
This is the only time this year that the result 666 occurs for two consecutive days.
 
168 + 169 equals: 337. This is the 8th Star of David number (including unity).
 
261 + 262 equals: 523. This is the 100th prime number and also the sum of the trinity reductions for the gematrias of 'JESUS' and 'CHRIST'.
