That is comfortable: there is room for a recurring call without either side moving their day.

Questions
Dublin and São Paulo, explained
What is the time difference between Dublin and São Paulo?
There is no single answer, which is why most converters get this wrong for part of the year. São Paulo is 4 hours behind, 3 hours behind relative to Dublin at different points in the year. Right now it is 3 hours behind. The table on this page gives the exact dates for each.
Why does the difference between Dublin and São Paulo change?
Dublin moves between UTC+00:00 and UTC+01:00, while São Paulo stays on UTC-03:00 all year. A gap only stays fixed when both ends are fixed. Here one end moves, so the difference moves with it even though nothing changed at the other end.
When is the difference between Dublin and São Paulo unusual?
The shortest window runs from Sunday, 28 March 2027 to Saturday, 30 October 2027 — 217 days during which São Paulo is 4 hours behind relative to Dublin rather than the usual amount. Short windows like this are where recurring meetings break, because nobody thinks to check.
Does this account for daylight saving automatically?
Yes. Offsets come from your device's own copy of the IANA time zone database through the browser's Intl API, so they reflect whatever rules are current rather than a table bundled here that could go stale. Pick any date in the converter and it resolves that date's rules, not today's.
