UPSC CSE: the only calendar that counts is on upsc.gov.in

The Union Public Service Commission publishes an annual Examination Calendar and, separately, the detailed Civil Services Examination notification โ both only on upsc.gov.in. The calendar gives the Prelims date and the notification date months in advance; the notification itself carries eligibility, the number of attempts, the age band, the vacancy count and the exact application window.
A wrong eligibility assumption can cost an attempt
For an exam with a fixed number of attempts and a strict age limit, work from the official document, not coaching rumours. Verify the Prelims date, the Mains date and the application deadline directly from the PDF on upsc.gov.in, and re-check if you see any 'revised date' claim elsewhere.
The sequence never changes: Prelims (a qualifying screen) โ Mains (written, merit-deciding) โ Personality Test (interview). The Prelims is the filter that decides everything else, and General Studies Paper 1 plus CSAT both have to be managed under time pressure.
Build the habit early
Build the General Studies habit early rather than cramming after the notification. Review the UPSC CSE syllabus, use the previous-year Prelims cut-offs to gauge the target, and take a free UPSC Prelims practice set on Kamiyab. Consistent daily practice, not last-minute volume, is what carries candidates through the Prelims filter.
