Passover always begins on the same date on the Hebrew calendar: the 14th of Nissan.
In the Hebrew calender, Passover or Pesach begins on the fifteenth of Nisan. This year (2010) it begins in the evening of March 30th. Either March or April

In 1998, April 11th was Shabbat and also the first day of Passover. It happens, but not very often.
