For aspirants aiming to don the uniform and serve the nation, the Combined Defence Services (CDS) examination is a pivotal gateway. Conducted twice a year by the Union Public Service Commission (UPSC), the CDS Exam selects candidates for commissioning into the Indian Military Academy, Indian Naval Academy, Air Force Academy, and Officers’ Training Academy. Success in this highly competitive exam hinges not only on rigorous preparation but also on meticulous planning, which begins with knowing the exact schedule. Missing a deadline for the application forms or being unaware of the exam date can derail an entire year’s worth of effort. This guide provides a definitive, consolidated resource for all crucial dates, notification details, and application procedures for the UPSC CDS I and II examinations in 2025.

Understanding the Combined Defence Services Examination
The Combined Defence Services (CDS) Examination is a national-level competitive exam managed by the UPSC. Its purpose is to recruit commissioned officers for various branches of the Indian Armed Forces. Candidates who qualify the written exam are called for an extensive interview by the Services Selection Board (SSB), a comprehensive personality and intelligence test. The final selection is based on performance in both the written test and the SSB interview.
Why Timely Information on CDS 2025 is Crucial for Aspirants
In an exam where preparation is measured in months, every day counts. Knowing the official dates allows a candidate to structure their study plan effectively. It helps in creating a reverse-engineered timeline, allocating specific periods for covering the syllabus, revision, and mock tests.
