Time-zone overlap for London team working with India / US?

From Ahmedabad (IST, UTC+5:30) to London (GMT/BST, UTC+0 or +1), the overlap is 4-6 hours per day, roughly 1 PM IST = 8:30 AM GMT (London just waking up), 7 PM IST = 1:30 PM GMT (London lunch). We schedule daily standups at 4 PM GMT (= 9:30 PM IST) so your London team gets a clean end-of-day handover. For London ↔ Dublin / Paris / Berlin, that's same business day (0-1 hr offset). For London ↔ US East Coast, that's 5 hours ahead (London 2 PM = NYC 9 AM), we can run trilateral calls comfortably. For London ↔ US West Coast (8 hours ahead), the only overlap is London 5 PM = SF 9 AM, so we run it async with Loom recaps + written EOD notes. London is the best timezone hub for global Magento work, sits in the middle.
