Hello there. Hope you are doing good. I would like to tell you that JAC has not announced the date sheet for 12th exams yet. It will be announced by the third week of December. Jharkhand Academic Council will release the exam ate sheet on their official website i.e jac-jharkhand.gov (//jac-jharkhand.gov) .in. The students will be able to download the pdf for date sheet directly from the link given on the official website.

I would suggest you to keep a check on the official website regularly for any updates regarding the date sheet.

I hope you found this answer helpful. Good luck for your future.
