The JEE Main 2027 Session 1 examination dates have been officially released by the National Testing Agency (NTA) in its national examination calendar. According to the official notification published on nta.ac.in, the first session of the Joint Entrance Examination (Main) 2027 will be conducted between January 22 and January 30, 2027 (specifically January 22, 23, 24, 28, 29, and 30, with January 31 reserved as a buffer day). Engineering aspirants targeting admissions into NITs, IIITs, and CFTIs or aiming to qualify for JEE Advanced 2027 can now align their preparation with a verified 120-day revision roadmap.
Latest status — verified on September 22, 2026: NTA has officially confirmed the Session 1 examination dates for JEE Main 2027 as January 22, 23, 24, 28, 29, and 30, 2027. Online application forms are scheduled to open in October 2026 on the official portal at jeemain.nta.nic.in.
Here are the 3 most important takeaways every engineering aspirant should focus on today:
- Fixed January Exam Window: Session 1 takes place in late January 2027 across two daily shifts (Morning: 9:00 AM to 12:00 PM; Afternoon: 3:00 PM to 6:00 PM) in computer-based test (CBT) mode.
- 75% Board Eligibility Enforced: Candidates must score a minimum of 75% aggregate marks in Class 12 (65% for SC/ST) or rank in the top 20 percentile of their respective qualifying board for NIT/IIIT/GFTI admission.
- January Percentile Advantage: Historical data shows that Session 1 provides the highest percentile per raw score because fewer students complete the full syllabus by January compared to April.

Why Session 1 Gives You a Higher Percentile Advantage
Many students make the mistake of treating the January attempt as a trial run and waiting for April. However, data from previous years clearly shows why you must target your maximum score in Session 1:
- Lower Competition Benchmark: In January, many Class 12 board students have not finished their syllabus or started mock testing. Hence, a raw score of 180–190 marks often yields a **99+ percentile** in January, whereas the same percentile in April may require 210–220+ marks.
- Board Exam Freedom: Securing a 99+ percentile in January relieves immense pressure, allowing you to focus entirely on your Class 12 board examinations in February/March and JEE Advanced in May.
- Best of Two Scores: NTA considers the higher of your two session percentiles for the final All India Rank (AIR). Scoring high early guarantees safety.
