The main phone office in Chania is open from very early morning to midnight for international calls, telegrams (who needs this nowadays?) and similar services. The administrative offices of OTE are open in the morning only.
Pharmacies keep normal shop hours Monday to Friday. They are closed on Saturdays. If you need a chemist on closing days or at night you can see which one is open (there are generally a few in larger towns) in the list displayed in the window of every pharmacy. The list is in Greek however. The best solution is probably to take a taxi to the nearest one. An alternative is to find the open pharmacy online (for Chania only).
There is almost always a kiosk open somewhere, night and day, at least in the cities
