When Bengaluru and Chicago can actually talk
On a standard 09:00–17:00 day there is no overlap at all between Bengaluru and Chicago.

Themeeting planner shows how much either side has to stretch, and who is affected least.
Calculated for Monday, 14 September 2026. Because the gap changes during the year, this window moves with it — the planner recomputes it for any date you pick.
Questions
Bengaluru and Chicago, explained
What is the time difference between Bengaluru and Chicago?
There is no single answer, which is why most converters get this wrong for part of the year. Chicago is 11 hours 30 minutes behind, 10 hours 30 minutes behind relative to Bengaluru at different points in the year. Right now it is 10 hours 30 minutes behind. The table on this page gives the exact dates for each.
Why does the difference between Bengaluru and Chicago change?
Bengaluru stays on UTC+05:30 all year, while Chicago moves between UTC-06:00 and UTC-05:00. 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 Bengaluru and Chicago unusual?
The shortest window runs from Monday, 2 November 2026 to Sunday, 14 March 2027 — 133 days during which Chicago is 11 hours 30 minutes behind relative to Bengaluru 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.
