Delete records that do not belong to that day

i have a requirement to delete records that do not belong to that day. For example in a file that came on July 31st ,2018 there are records that belong to Aug 1st,2018 as well and I want to find and delete those records. I want to delete anything with 01-Aug-2018. I have several files like that. I need a script that gets the first line second column that is date and add one day to it and delete that record.in this case all 1st Aug records should be deleted. Thank you in advance for your help.

Code:
a,31-Jul-2018 12:00,14
a,31-Jul-2018 12:01,13
a,31-Jul-2018 12:02,15
a,31-Jul-2018 12:03,19
and so on
