What Is the Anna University Academic Calendar?

The Anna University Academic Calendar is the official document that outlines the entire academic year's schedule for all affiliated engineering colleges in Tamil Nadu. It includes semester start and end dates, internal assessment schedules, exam windows, holidays, and other important academic milestones.

Every student — from first year to final year — should be thoroughly familiar with this calendar to plan their studies, attendance, and personal commitments effectively.

Structure of the Academic Year

Anna University follows a semester system, with two main semesters in each academic year:

  • Odd Semester (July – November): Covers Semesters 1, 3, 5, and 7 for UG students
  • Even Semester (January – May): Covers Semesters 2, 4, 6, and 8 for UG students

Attendance Requirements

One of the most critical aspects of the Anna University academic calendar is the minimum 75% attendance requirement. Students who fail to maintain this in any subject are not permitted to appear for the semester examination in that subject, resulting in an automatic "detained" status.

Use the academic calendar to track working days, holidays, and plan any leaves carefully to avoid falling below this threshold.

Internal Assessment (CIA) Schedule

The Continuous Internal Assessment (CIA) typically consists of:

  • CIA-1: Covers the first unit/module of the syllabus — held around 5–6 weeks into the semester
  • CIA-2: Covers subsequent units — held around 10–11 weeks into the semester
  • Model Exam / Practical Exams: Conducted before the university exams begin

Holidays and Special Occasions

The academic calendar accounts for all public holidays declared by the Tamil Nadu government, national holidays, and university-specific occasions. Colleges may additionally declare local holidays for events like college day, sports day, or cultural festivals — these are announced separately by individual institutions.

How to Access the Official Academic Calendar

The academic calendar is available on the Anna University official website at annauniv.edu. It is typically released before the start of each academic year (around June–July). Look for the "Academic Calendar" or "Circulars" section under the Academic Affairs menu.

Why the Academic Calendar Matters

Planning your academic year with the calendar in hand allows you to:

  • Schedule study leaves before CIA tests
  • Plan project work and submissions without clashing with exam windows
  • Avoid attendance shortages during long holidays
  • Prepare for university exams well in advance
