February 1st, 1998 is Sunday. What day is February 1st, 2006? What year is 2008

Because the year of 2000 and 2004 is leap year 1, (365 * (2006-1998) + 2) / 7 = 417, more than 3 are not divided completely, so it is Wednesday and Tuesday, or 365 / 7 = 52 more than 1. If there is no leap year, every extra year, the week will be pushed back one day. If there is a leap year, the year after the leap year will be pushed back one day
