letos

1. this summer; last summer
   Letos smo bili na moru u Grčkoj. — This summer we went to the seaside in Greece.
   Letos je bilo užasno vruće. — It was terribly hot this summer.
   Već je februar, a letos smo se tek upoznali. — It's already February, and we only met last summer.

Refers to the current or most recent summer: in summer and autumn it means this year's summer, in winter and spring the summer just past, even if it fell in the previous calendar year; compare zimus, proletos, jesenas.
