The development comes weeks after the Government resolved to reopen schools gradually with adherence to Covid-19 preventive measures.
Schools were closed in March, when students in primary and secondary were remaining with less than a month to complete the first academic term.
According to a statement by the ministry under the new calendar, all students will begin from the second term.
The ministry also noted that students allowed to resume studies are those in upper primary, all levels of secondary, TTC and TVET.
Students in primary 5 and 6, those in senior 3, 5 and 6, those in TVET and students in TTC will resume second term studies on November 2 and end on April 2, 2021.
During the period, the students in the above classes will have four weeks for revision, assessment and remedial learning activities, before learning content of the second term.
For primary four pupils and students in senior one, two and four, they will kick-off their second term on November 23 and end on April 2.
All students will have a two-week holiday on April 3 through April 15.
The third term will last for 12 weeks, starting on April 19 and end on July 9, next year.
Mineduc explained that primary national examinations are scheduled to take place on July 12, 2021 and end on July 14.
Meanwhile, national examinations for secondary schools, TTC and TVET students are scheduled on July 20 and end on July 30, next year.
The ministry noted that lower primary and pre-primary will resume studies later, adding that the details of their calendar will be communicated in due time.
In the meantime, the online learning will continue to support learning for those levels.
So far, higher learning institutions in Rwanda have already resumed their studies.
