AT contributor Andrew Walden noted something very odd indeed in an article in the Hawaii Free Press:
Islamists have just tricked the Hawaii Legislature into celebrating Islam on September 11.
By a 22-3 vote the Hawaii Senate May 7 approved House Concurrent Resolution 100 which designates September 24, 2009 as Islam Day. The State House had quietly approved the measure without dissent March 17.
Introduced March 4 as HCR100 by Reps Faye Hanohano (D-Puna), Lyla Berg (D-Hawai`i Ka`i), and Della Au Belatti (D-Makiki) HCR100 proposed Islam Day to be "November 21, 2009, marks the anniversary of the founding of Islam...." But that was soon amended to HCR100HD1 which intones, "the Prophet Mohammad left his house to migrate to Madinah and reached Quba in the vicinity of Madinah on the 12th day of Rabi ul-Awwal according to the lunar calendar, or September 24th according to the Gregorian calendar, thereby marking the birth of Islam...." (Emphasis added)
This is false. September 24th is the date of Mohammad's arrival in Medina according to the old Julian calendar -- which is 13 days behind the modern Gregorian calendar. The fact that "Gregorian" is mentioned in the resolution implies that somebody was considering the two calendars.
Had the Hawaii legislature intended to mark the Julian date September 24 they would have picked the Gregorian date October 7, 2009 for Islam Day. Had they wished to mark the date celebrated each year by Muslims, that would have been the "12th day of Rabi ul-Awwal" -- March 9, 2009.
But instead they picked the modern Gregorian date September 24, 2009. This day corresponds to no holiday in the Islamic calendar. But on the Julian calendar it is September 11, 2009.

Meanwhile the Islamists are laughing.
Julian-Gregorian Calendar converters:
This can be considered the ultimate inside joke. Islamists are laughing their heads off. In an email to me, Andrew comments:
We are "celebrating" Islam Day on Sept 24 of the calendar we all use today which is September 11th of the Julian (ie Byzantine) calendar. So the new Rome is celebrating Islam on the day of the beginning of its own defeat (in their dreams) as expressed in the calendar of the old Rome (Constantinople) which was finally defeated by Islam in the 1400s.
