⚠️
Watch out for DST mismatch weeks. The US and Europe change their clocks on different dates, and for a few weeks the gap between them is an hour smaller than usual. In 2026 that is March 8 to 28 in spring and October 25 to 31 in autumn, when New York and London are 4 hours apart instead of 5. The live clocks on each page use your browser's time zone data, so they follow the real dates.
