Need advices on how to convert into standard date format(MM/dd/yyyy) from June 6, 2021 and 24th May 2021, 02:30am PST and July 24th, 2021 02:00 PM PT

@ks185332 - Please check this…

DateTime.ParseExact("June 6, 2021", {"MMMM d, yyyy","dd MMMM yyyy, hh:mmtt PST","MMMM dd, yyyy hh:mm tt PT"}, new CultureInfo("en-US"),DateTimeStyles.None).tostring("MM/dd/yyyy")

For the 2nd and 3rd dates, you have to replace th,rd,nd and st values before passing to the above code…

Hope this helps…
