AEST vs GMT
Australian Eastern Time (AEST/AEDT) is UTC+11 in winter and UTC+10 in summer. Greenwich Mean Time / UK (GMT/BST) is UTC+0 in winter and UTC+1 in summer.
Because the two regions change their clocks on different dates, the gap changes during the year: 11 hours behind in the northern winter and 9 hours behind in summer, with a few weeks in spring and autumn where it's an hour different again. The converter uses the exact rules for the date you choose.
