The two cities side by side. The January column uses the winter offsets (Chicago UTC−06:00, Los Angeles UTC−08:00); the July column uses the summer offsets (Chicago UTC−05:00, Los Angeles UTC−07:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Chicago and time in Los Angeles — explain each city's time zone, offsets and daylight saving in full.
The time difference between Chicago and Los Angeles
The difference is constant: Los Angeles is 2 hours behind Chicago on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in Chicago is always 07:00 in Los Angeles. The reason the difference never changes is that both cities observe daylight saving and change their clocks on the same dates.
To convert a time, add the difference: 09:00 in Chicago is 07:00 in Los Angeles in January and 07:00 in July; 17:00 in Chicago — the end of the working day — is 15:00 in Los Angeles in January and 15:00 in July. To go the other way, subtract it: 09:00 in Los Angeles is 11:00 in Chicago in January. The time difference calculator does the arithmetic for any date, and the UTC to Los Angeles page gives the full conversion table for Los Angeles.
Meeting overlap between Chicago and Los Angeles
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in Chicago's working day and shows what time they are in Los Angeles.
January
| Chicago time | Los Angeles time | Both working? |
|---|---|---|
| 09:00 | 07:00 | Yes |
| 10:00 | 08:00 | Yes |
| 11:00 | 09:00 | Yes |
| 12:00 | 10:00 | Yes |
| 13:00 | 11:00 | Yes |
| 14:00 | 12:00 | Yes |
| 15:00 | 13:00 | Yes |
| 16:00 | 14:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Chicago time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Chicago time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in Chicago and Los Angeles
Chicago observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−06:00 to UTC−05:00.
Los Angeles observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−08:00 to UTC−07:00.
The difference never changes, so there is no date on which a standing meeting moves. That does not mean the difference is the same as the difference with a third city — the difference between Chicago and London, for example, may still move when London changes its clocks. The individual DST pages — Chicago DST 2026 and Los Angeles DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Chicago (07:00–15:00 in Los Angeles). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in Chicago it is 07:00 in Los Angeles in January; when it is 12:00 in Chicago it is 10:00 in Los Angeles; when it is 17:00 in Chicago it is 15:00 in Los Angeles. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling inside the Americas is usually straightforward: the difference between Chicago and Los Angeles is small, and the working days overlap for most of the day. The main thing to check is daylight saving — not every place in the Americas observes it, and the ones that do change on different dates (the United States and Canada in March and November, Chile in September and April, Mexico not at all since 2022).

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in Chicago and time in Los Angeles — explain each city's time zone, and the DST pages — Chicago DST 2026 and Los Angeles DST 2026 — give the exact change dates.
