Of course, this causes a problem for making the universe even younger than the YEC's claim. Remember, there is a geneology from Adam to Noah and from Noah to Abraham. There's only about 1300 years from the flood to the founding of Solomon's Temple and another 1500 years from the creation to the flood. If they're using a lunar calendar, this puts creation at about 1200 BCE and we know that the earth is older than that...the Great Pyramid dates to the 26th century BCE.
