Don't confuse with

二十日はつかN5
２５日 (にじゅうごにち) is read regularly, while 二十日 (はつか) uses an irregular traditional reading for the 20th day/20 days, so learners often mix up the reading pattern.
２４にじゅうよっ日か
２５日 (にじゅうごにち) uses the plain にち reading, whereas 二十四日 (にじゅうよっか) for the 24th/24 days uses the irregular よっか pattern, so the two are easy to confuse when reading dates aloud.

Written forms

２５にじゅうご日にち
Common numeric spelling for both a date, the 25th, and a duration of 25 days; full-width digits are used.
二に十じゅう五ご日にち
Kanji numeral spelling, used especially in more formal writing or when dates are written out.
二五日にじゅうごにち
Compressed kanji-numeral spelling; much less common than ２５日 or 二十五日.

Etymology

Transparent compound of the number 二十五, 'twenty-five', plus 日, 'day'. This is a counting and date expression rather than a separate historical idiom.
