CBSE Class 12 Board Exams 2027 begin on Tuesday, February 16, with Physics (subject code 042). The Central Board of Secondary Education released its official Class 10 and Class 12 timetable on November 6, 2026. For Class 12 students, the datesheet is useful not only for checking exam dates but also for planning revision across Science, Commerce and Humanities subjects. The Physics paper is scheduled from 10:30 AM to 1:30 PM. Students must check the individual timings of all other subjects in the official PDF rather than assume that every paper lasts three hours.

This table lists selected high-interest papers, not all 121 Class 12 subjects. The full timetable also covers languages, skill subjects, optional subjects and other examinations. CBSE states that every examination will start at 10:30 AM IST, while the finishing time depends on the paper. Candidates should match the datesheet with their own registered subjects and admit-card particulars.
How Much Preparation Gap Is Available Between Major Exams?
| Exam sequence | Date difference | Full days between papers |
|---|---|---|
| Physics → Chemistry | February 16 to February 27: 11 days | 10 days |
| Chemistry → English | February 27 to March 5: 6 days | 5 days |
| English → Mathematics | March 5 to March 9: 4 days | 3 days |
| Mathematics → Biology | March 9 to March 25: 16 days | 15 days |
| Accountancy → English | February 23 to March 5: 10 days | 9 days |
| Economics → Business Studies | March 16 to April 1: 16 days | 15 days |
The date difference counts the calendar distance between two exam dates; the final column excludes both examination days and shows the complete days in between. These are examples for students taking those subject combinations, not guaranteed free days for everyone. A student with Physical Education, a language, Psychology, Computer Science or another elective may have a paper during the apparent gap. Always calculate your personal revision window from every subject on your admit card.
Physics on February 16: What Should Students Prioritise?
Physics is the opening paper in the published Class 12 schedule, leaving no preceding Class 12 examination within the main timetable for a final between-paper revision. Complete NCERT concepts, formula revision, diagrams, derivations and numerical practice before the board examinations begin. Use timed previous-year and CBSE sample questions to identify weak chapters. In the final week, prioritise solving mistakes and revising important definitions rather than attempting unfamiliar material in bulk. The 10 full days between Physics and Chemistry can support a targeted Chemistry revision plan, but only after accounting for any optional papers scheduled in that period.
Stream-Wise Preparation Strategy for Class 12
Science students should complete basic preparation in Physics, Chemistry and Mathematics or Biology well before February. Use any subject gaps for chapter-wise error correction, sample papers and formula or reaction revision. Commerce students should track Accountancy on February 23, English on March 5, Economics on March 16 and Business Studies on April 1, along with Mathematics or other electives when applicable. Humanities students should organise their preparation around Geography, Psychology, English, Political Science, History and Sociology according to their actual combinations. Each stream benefits from a study timetable that includes practice, revision and rest rather than treating long gaps as extra time to begin the syllabus.
How to Download the Official CBSE Class 12 Datesheet 2027
Visit the official CBSE website, open the latest announcement for the Class X and XII Board Examinations 2027 datesheet, and download the PDF. Navigate to the Senior School Certificate (Class XII) examination schedule and find your subjects using their names or codes. Note the exam date, reporting instructions and paper duration. Save a copy and confirm any subsequent CBSE notices before finalising a study plan. The datesheet was issued on November 6, 2026, and this article uses that version.
Important Instructions for Students and Parents
CBSE says the 2027 datesheet was prepared after considering school-submitted subject combinations and the tentative dates of major entrance examinations. Students should nevertheless check their own paper combinations carefully and allow for travel, practical examinations, school instructions and admit-card rules. Neither a broad timetable nor a preparation-gap calculation guarantees that a student has no other exam on an intervening date. If CBSE revises a date or timing later, the latest official circular will take precedence. Parents can help students maintain a realistic daily revision schedule rather than focusing only on how many days separate two high-profile papers.
