time duration filter?

[gigaimage]

fd ^Book.*\.* --change-older-than 3weeks --newer 2026-05-01 -e pdf

Is there a better way to pass such time duration filter?

proly worth adding something like a “—FromTo” flag that takes two args?
fd ^Book.*\.* --FromTo 05-01-2026 05-30-2026 -e pdf

You can already express the interval by combining the two built-in modification-time filters. They are ANDed together:

fd '^Book.*' -e pdf   --changed-within 2026-05-01   --changed-before 2026-05-30

• --changed-within <date|duration>: modified newer than the value
• --changed-before <date|duration>: modified older than the value

So the corrected relative version of your first command is:

fd '^Book.*' -e pdf   --changed-within 2026-05-01   --changed-before 3weeks

If you mean the whole month of May, use an exclusive upper boundary of June 1:

fd '^Book.*' -e pdf --changed-within 2026-05-01 --changed-before 2026-06-01

That avoids accidentally excluding most of May 30 when a bare date is interpreted at midnight. A separate --from-to option would therefore duplicate the existing pair.

The current option names and accepted <date|dur> values are shown in the fd command-line options.
