About ACDT
Australian Central Daylight Time (ACDT) is UTC+10:30. It is used in Adelaide in summer.
Australian Central Daylight Time is UTC+10:30, what South Australia keeps from October to April. Darwin stays on ACST through the summer, so for those months two cities in the same nominal zone are an hour apart — the only reason to be precise about which of the two abbreviations a meeting invitation carries.
About EEST
Eastern European Summer Time (EEST) is UTC+3. It is used in Athens, Helsinki and Kyiv in summer.
Eastern European Summer Time is UTC+3, the summer clock for Greece, Finland, Romania, Bulgaria and the Baltics. In summer it coincides with Moscow Time, which does not move — so Helsinki and Moscow agree for half the year and differ by an hour for the other half, without Moscow having changed anything.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EEST switches to EET (UTC+2) from late October to late March. So the 7.5-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
ACDT does not shift, so the whole change comes from one side. A recurring meeting fixed in ACDT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
