 FACT: The phrase "Tria mera" isnt proper greek, nor is it how  "third day" is in the Bible. In greek "third day" is "triti mera".  "Tria" means three and "triti" means third. The actual phrase from  the bible is also "triti mera". Furthermore, if you try to turn  "Tria mera" to numerical value using the greek numericals, you get  557 and not 666.
