The best time to meet is 8:00 AM to 11:00 AM in Medellín, which is 3:00 PM to 6:00 PM in Cairo. With about 3 hours of overlap, there's comfortable room for a daily stand-up — 8:00 AM in Medellín / 3:00 PM in Cairo works well. One seasonal catch: Cairo springs forward and falls back, but Medellín doesn't, so the gap changes by an hour for several months of the year.
