What is the command in Linux to find files created on a specified day (say, February 3) of any year?

Answer 1

find . -exec ls -l --time-style=full {} \; | grep -P '\d{4}-02-03'

Answer 2

Looks for files created after September 29, 2008 (but not after September 30 of the same year, inclusive):

find . -type f -newerc 2008-09-29 ! -newerc 2008-09-30

Answer 3

I didn’t use it, I just found it in a search engine:
