Dear student,

I hope you are doing well about your question, I know it can be a bit difficult to remember the dates, I myself forget such stuff. To remember such data I follow the official pages on Instagram that helps me to be updated. Or I keep visiting the official website after 2 or 3 days to keep in touch this is 1 way I can keep track. Another option is too keep asking ur classmate or teachers.

Hope this helps !!
