Hi friends! Greetings.
I recently came across a website " worldslastchance dot com" wherein they claim that the 7th day sabbath is not falling on saturday, but on 8,15,22,29 of the month. Please see for yourself what they claim. Please respond to me with your comments:

WLC strives to follow all Biblical truth. The WLC team has made the shocking discovery from the Bible that the seventh-day Sabbath cannot be found except on the Creator's calendar.
In His calendar, the weekly Sabbath always falls on the 8th, 15th, 22nd, and 29th of each month.
Since the mark of the beast is received if one does not worship the Creator on His true Sabbath day, and because WLC infinitely cares about our salvation and yours, WLC is offering US$1,000,000 (one million) to anyone who can convincingly demonstrate from the Scriptures that the true seventh-day Sabbath has ever been recorded in the Bible to have fallen on any other dates than those listed above. unquote
