TT 2013 will feature the same race programme as this year.
There will be two sidecar races and the same solo classes - Superbike, Supersport, Superstock, Supertwin, Senior and TT Zero.
The decision to make no changes comes after organisers consulted with teams, competitors, manufacturers and fans.
The first practice session will be on Saturday, May 25 and Senior Race Day is Friday, June 7.
TT and Motorsport Development Manager Paul Phillips says everyone seems happy with the current timetable of races:
Ten-man FC Isle of Man secure late draw against Burscough
Hockey: New pre-season tournament taking place today
Rugby: First match of new season to take place today
Hockey: 2026 Mixed season fixtures announced
