Waking hours
We assume people are up from 7:00 to 22:00, and that 9:00 to 21:00 is a fair time for a call. Change it if they keep other hours.
About this pair
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.
