•What Do EST and AEST Actually Mean?
EST — Eastern Standard Time (EST, UTC-5) runs part of the year; the rest of the year the same clocks are on Eastern Daylight Time (EDT, UTC-4) instead. People casually say "EST" for both — SyncHours' scrubber below already resolves whichever one is actually in effect for the date you pick.
AEST — Australian Eastern Standard Time (AEST, UTC+10) runs part of the year; the rest of the year the same clocks are on Australian Eastern Daylight Time (AEDT, UTC+11) instead. People casually say "AEST" for both — SyncHours' scrubber below already resolves whichever one is actually in effect for the date you pick.
Timezone abbreviations like these aren't globally unique — several regions reuse the same three or four letters for unrelated zones. The scrubber above is anchored to real IANA timezone data (America/New_York and Australia/Sydney) rather than the abbreviation text itself, so there's no ambiguity in the actual conversion.
