The biggest bank in Croatia, like Zagrebačka banka or Privredna banka have their seats in Zagreb so they have a lot of branch offices in town. All other important banks have their branch offices in Zagreb. Banks are open from 8 a.m. to 7 p.m. on work days, Monday to Friday, and from 8 a.m. to 1 p.m. on Saturdays.

At the Main Railway station there is 24 hour Exchange Office.
