"%Y%m%d"

is a common Python `strftime`/`strptime` date format for: *

%Y

= 4-digit year *

%m

= 2-digit month *

%d

= 2-digit day So it produces/parses dates like:

20260721
20250103

In Python:

from datetime import datetime

s = datetime.now().strftime("%Y%m%d")
print(s)

If you want, I can also show: * how to parse this into a

datetime

* how to use it in a Prefect flow * how to convert it to

YYYY-MM-DD
