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:
Joe Yeardsley's TT excitement after 'emotional rollercoaster' year
Rugby: Nomads Under-15's taking on Cheshire Junior Shield Final
Football: Hospital Cup & Junior Cup reach quarter-finals stage
Cycling: IoM Youth and Junior Tour returns this weekend
Squash: Isle of Man contests European championships in Bucharest
