The appearance of the New Moon in Israel is what determines the 1st day of each Hebrew month. Therefore, Nisan 1 must not only fall on a Thursday, but also on the New Moon that determines that it is in fact the first day of the month of Nisan. The Hebrew calendar, thus God's calendar is a Lunar calendar, not a solar calendar.
