adverb. (on) any day

adverb. (on) every day
The correlative ᴹQ. qáqanar “everyday” or qáqaryas “on every day” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/110), a combination of ᴹQ. qa(qe)- “every” and ᴹQ. -ar(yas) “day”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to an adverb ᴺQ. ilaurë “every day, daily” using il- “every” and aurë “day”, inspired by later adjective ilaurëa “daily”.
The correlatives ᴹQ. immar “any day” and immaryas “on any day” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/109), a combination of ᴹQ. imma “any” and ᴹQ. -ar(yas) “day”. As originally published in PE23, the second form was given as immanyas with an n, but Christopher Gilson confirmed the actual form was immaryas in private correspondance consistent with similar words in DRC.
Neo-Quenya: Since ᴹQ. imma “any” too closely resembles the later prefix Q. im- “same”, for purposes of Neo-Quenya I would update this to ᴺQ. ainaurë “any day” using Q. aurë for “day” and the hypothetical prefix ᴺQ. ai(a)- “any”; see that entry for discussion.
