"The Nation" noted that the timing of the coup contains many instances of the number nine, a highly auspicious number in Thai [[numerology]]. The coup occurred at the 19th day of the 9th month of [[Buddhist Era]] 2549. Coup leader Sonthi Boonyaratglin made a major public announcement on the morning after the coup at 9.39 am. "The Nation" earlier indicated 09:16 as the time for Sonthi's press conference and the [[Buddhist calendar]] is in line with the [[Gregorian calendar]] only since 1941.
