Hello aspirant,
Basically, pharmacy counselling starts a few weeks after the declaration of entrance exam results. The exact start date for pharmacy counselling varies depending on several factors:

State: Different states have their own counselling processes and schedules.

Entrance Exam: The counselling usually starts after the declaration of results for entrance exams like JEE Mains, NEET, or state-level pharmacy entrance exams.

Institute: Individual colleges or universities may have their own counselling schedules.

I hope this information helps.
