The working week is Monday to Friday on both sides: roughly 08:00–17:00 in Zurich and 09:00–18:00 in Istanbul. Watch for Swiss National Day (1 August) and Easter Monday (March or April) in Zurich and Ramadan Feast (end of Ramadan, three days) and Sacrifice Feast (four days, roughly 70 days later) in Istanbul. Replies slow in Zurich during late July to mid-August, and Christmas to early January and in Istanbul during the Sacrifice Feast week.
