We have very little evidence for Lindórië's dates, but we do know that her elder brother Eärendur served as Lord of Andúnië during the reign of Ar-Sakalthôr (II 3033 - II 3102), which implies that Lindórië herself lived during the thirty-first century of the Second Age. Also notable is the fact that Lindórië's daughter Inzilbêth married Ar-Sakalthôr's son Ar-Gimilzôr, who was born in II 2960. Assuming Inzilbêth's own birthdate was comparable to her husband's, it seems that Lindórië must have been alive during the thirtieth century, suggesting that her own birth date would have been close to (very approximately) II 2900.

The meaning of Lindórië's name is not explained, though it apparently contains the Elvish element lind- for 'song' or 'music'. The -órië ending is much less certain, but is perhaps connected to the verb 'to rise', in which case the name Lindórië would mean something like 'rising song'.
