Search for Gmail messages received on a particular date

Question

I want to search for Gmail messages received on a particular date.

I can find messages received before YYYY/MM/DD using:

Before:YYYY/MM/DD

I can find messages received after YYYY/MM/DD using:

After:YYYY/MM/DD

But how can I find messages received after one date but before another date? The following search seems to find messages received on 2021/07/01 and on 2021/06/30:

Before:2021/07/02 After:2021/06/30

How do I find only messages received on 2021/07/01?

Answer 1

I tried:

 after:2021/07/01 before:2021/07/02 

I used the assumption that the time of day used was midnight.

So I was asking for everything between July 1st 2021 00:00:00 but before July 2nd 2021 00:00:00
