Left out or changed by Shishya: 25 well-known days picked from ~250 on the page, one per date so the reverse question has a single answer (e.g. World Poetry Day and International Day of Forests share 21 March with others, so left out). Agency tags like [WHO]/[UNESCO] dropped from names. World Migratory Bird Day left out (page lists it twice, under May and October). Page read via HTTP GET and parsed name -> date; page prints no last-updated date.

Names and spellings are kept as the source prints them. Spotted a change on the official page? The list is re-read from the source, never from other sites.
