Ah, sorry for the noise, I figured out what my problem was. I'd tried specifying :tstart and :tend, per the manual, but my initial attempt to do so resulted in the following error:
org-clock-get-table-data: Wrong type argument: stringp, <2025-04-06 However, after rereading the manual more closely, I realized that I'd forgotten to quote the time strings. Specifying: #+BEGIN: clocktable :scope file :maxlevel 2 :tstart "<2025-04-06 Sun>" :tend "<2025-04-12 Sat>" got me the result I was looking for. Thanks, Rohit
