The correlatives ᴹQ. manar and manaryas “on what day” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/109), a combination of interrogative ᴹQ. ma and ᴹQ. -ar(yas) “day”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. manaurë using Q. aurë for “day”.
