# When can I ring Istanbul from Berlin?

Turkey keeps one time all year. The gap is smaller in summer, while Germany is on summer time, and grows by an hour in winter.

With so small a gap, almost any waking hour works for both of you. The table shows the few hours at each end of the day to leave alone.

## Through the year

We assume you are up from 7:00 to 22:00 and that 9:00 to 21:00 is a fair time for them to take a call. Change the hours in the tool above if they keep others.
