Best overlap: 8:30 AM to 12:30 PM in Manchester is 2:00 PM to 6:00 PM in Chennai.
The hours that work for both Manchester and Chennai are 8:30 AM to 12:30 PM (Manchester) and 2:00 PM to 6:00 PM (Chennai). With about 4 hours of overlap, there's comfortable room for a daily stand-up — 8:30 AM in Manchester / 2:00 PM in Chennai works well. One seasonal catch: Manchester springs forward and falls back, but Chennai doesn't, so the gap changes by an hour for several months of the year.
