Another oddity

Sanskrit <ahar->, <ahan-> "day" (I am not aware whether it is counted
among the original r/n-heteroclitic nouns, a small ancient group in
IE)

Basque <egur>, composite form <egun-> "day", member of a small group
of Basque nouns alternating in r/n.

The rest of either group don't seem to contain possible matches. The
Sanskrit root is by some linked to Germanic <dag-> "day", assuming a
d-prefix.
