Dates Change Each Year

While the general due dates for different kinds of taxes are set by the IRS and other agencies, the dates may vary for a particular year, if the due date falls on a weekend or a holiday. The IRS rule is that if a tax due date falls on a weekend or holiday, the due date is the next business day. So a tax due date of Sunday, April 15 would be moved to Monday, April 16 in that year.
