I've looked into this before and datapoints suggest that they go by month rather than calender day so technically if your 5th youngest account is going to turn 2 years on 5/15/2020, you are good to go on 5/1/2020 no matter what bureau they pull.
MyFico readers suggest waiting a full month to be on the safe side which is sound advice but sometimes you need to pull the trigger early so you can get your card before a trip or big spend that has a due date.

If the last account that will take me down to 4/24 was listed as opened on July 1, 2017 on my credit report, would I be ok to app for a Chase card now or do I need to wait until August 1st?
I would always go with the option that ensures a smoother process when applying.. I would wait for August also check the prequal (Or for checkmarks if you already bank with Chase).
