Languages & date formats
Each checked format multiplies the rows.
Numeric patterns
Language-agnostic. Generated once, in their own output group.
2-digit versions are added for the day-first and month-first patterns; year-first patterns are skipped (a 2-digit year-first date is ambiguous).
Date range
Every selected day of each checked month.
YouTube launched on February 14, 2005, and the first video was uploaded on April 23, 2005, so earlier years won’t match upload dates, only dates mentioned in titles.
1–31 keeps every day · 1–7 samples just the first week of each month.
Generates queries for just this one day.
Upload-date operators
Check both to limit each search to videos uploaded on that exact date, on top of the date appearing in the query.
Queries
Joined with | (OR). Empty fields are skipped.
Each becomes -term; multi-word entries are quoted, e.g. -"music video".

Encoded into YouTube’s sp parameter, same as the native filter menu.
