Hello, using datetime in R2021a brings an error while the same task works in R2017b, Is there a way to fix the issue in the newer version?
b=string('2004Q1');
In R2017b
c=datetime(b,'InputFormat','yyyyQQ')
c =
datetime
01-Jan-2004
In R2021a
c= datetime(b,'InputFormat','yyyyQQ')
Error using datetime (line 647)
Unable to convert '2004Q1' to datetime using the format 'yyyyQQ'.

That seems to have changed between releases. In R2021a, it’s necessary to use 'QQQ' to designate ‘long format’ quarters —
b=string('2004Q1');
c= datetime(b,'InputFormat','yyyyQQQ')
c = datetime
01-Jan-2004
See Format for details.

As always, my pleasure!
Yes. I linked to them in my Answer. (At least I believe that’s the information you want. If it isn’t, post back with a description, and I’ll look again.)

I tried but it still won't work: Unable to convert '2004Q4' to datetime using the format 'yyyyQQQ'.

That is a valid display format.
It is not a valid input format.
