Academic Calendar

The dates shown in the printable versions of the academic calendars take precedence over those displayed in the tables.

When June 24 and July 1 fall on a Saturday, each holiday is observed the previous Friday.

The INRS academic calendars do not apply to joint programs in earth sciences (INRS-Université Laval). For these programs, the calendar of the partner university applies.

Contact the Registrar’s Office if you want more information about academic calendars.
