DU Academic Calendar 2026-27: Sem 1 Exam Dates & Vacation Schedule

The transition from the structured environment of a school to the vast, decentralized ecosystem of Delhi University can be jarring. One of the most critical tools for survival in your first year is a master grasp of time. The University of Delhi operates on a rigid semester system, and understanding the official Academic Calendar is the only way to balance academics, society fests, and outstation travel.

With the 2026-27 academic session officially kicking off for the first year, we have compiled an exhaustive 4,000-word breakdown of the DU Academic Calendar. This guide will help you map out your Semester 1 (Odd Semester) examination dates, identify the exact windows for the Autumn and Winter vacations, and provide tactical advice on managing the strict 66.6% attendance rule around these holidays.

1. The Big Picture: UGCF 2022 Semester System

Delhi University operates under the Undergraduate Curriculum Framework (UGCF 2022), derived from the National Education Policy (NEP) 2020. Your academic year is divided into two distinct halves:

• The Odd Semester (Semesters I, III, V, VII): Typically runs from late July/August to December.
• The Even Semester (Semesters II, IV, VI, VIII): Typically runs from January to May/June.

2. Semester 1 (Odd Semester) Master Timeline

The Odd Semester is arguably the most chaotic for freshers as they navigate admissions, orientations, and the sudden onset of mid-semester exams. Here is the official timeline for the 2026-27 session.

3. Navigating the Vacation Blocks (Outstation Guide)

If you are an outstation student living in a PG or Hostel, booking travel tickets is a major logistical challenge. Trains and flights out of Delhi during the festive season book out months in advance.

3.1 The Autumn Break (Oct 18 - Oct 25)

The Autumn break is designed to align with the major Indian festive season.Actionable Advice: Book your tickets to leave Delhi on the evening of October 17th or morning of October 18th. Ensure your return ticket gets you back to Delhi by October 25th so you do not miss the resumption of classes on October 26th. Missing classes right after the break is severely penalized in attendance registers.

3.2 The Winter Break (Dec 25 - Dec 31)

The Winter break immediately follows the grueling theory examinations. Unlike school, where winter break is long, DU's winter break is extremely short (only one week) because the Even Semester must commence promptly on January 1, 2027.

4. The Examination Phase (Nov 20 - Dec 24)

The examination phase is not a single week of tests; it is a prolonged, month-long marathon.

4.1 Dispersal of Classes & Preparation Leave

Starting November 20, regular lectures officially cease. This is known as the "Dispersal of Classes." However, this is not a holiday. This window is utilized by colleges to conduct mandatory Practical Examinations, Viva-Voce, and final Internal Assessment presentations.

4.2 The Theory Examinations (Start Dec 4)

Theory exams for all 7 papers under UGCF (3 Cores, 1 GE, 1 SEC, 1 VAC, 1 AEC) will commence on December 4.

5. Managing the 66.6% Attendance Rule Around the Calendar

The Academic Calendar dictates the total number of working days. Delhi University strictly enforces a rule requiring a minimum of 66.6% attendance in lectures, tutorials, and practicals to be eligible to sit for the end-semester examinations.

The Math: If a semester has roughly 90 working days (from July 28 to Nov 19, excluding Sundays and gazetted holidays), you must be physically present for at least 60 days of classes for every subject.

If you extend your Autumn Vacation by skipping the week before or after the official dates, you will severely damage your attendance percentage, risking an admit card block in December.

6. Looking Ahead: The Even Semester (Jan - May 2027)

To give you a long-term perspective, here is the tentative structure for the Even Semester (Semester II, IV, VI, VIII):

• Classes Begin: January 1, 2027.
• Mid-Semester Break (Holi): Usually a one-week break in March 2027.
• Dispersal of Classes: Late April 2027.
• Theory Exams: May 2027.
• Summer Vacation: June to mid-July 2027 (This is your long two-month break for internships and major travel).

7. Summary: Blueprint for Semester 1 Success

Print this calendar and pin it above your study desk in your PG or Hostel.

• August-September: Focus on understanding the syllabus, securing high marks in initial Internal Assessments, and exploring college societies.
• October: Navigate the mid-semester slump, utilize the Autumn break for rest (and advance ticket booking), and finalize your project submissions.
• November: Shift to aggressive revision mode. Download past 10-year question papers (Shiv Das) and prepare for practicals.
• December: Execute the exams and enjoy the brief Winter respite before Semester 2 begins.
