America/Kentucky/Monticello

The America/Kentucky/Monticello time zone (IANA zone identifier America/Kentucky/Monticello) covers 2 USPS ZIP codes with a combined population of 20,195. Time-zone data on this page is tagged per ZIP rather than per state — several U.S. states sit across zone boundaries (Indiana, Kentucky, Tennessee, Oregon, Idaho, North Dakota, and others), so a ZIP-level tz field is the only way to answer correctly "what time is it in ZIP america-kentucky-monticello?" for applications like scheduling, shipping, or call-center routing.

Each ZIP in this view stores its canonical IANA zone string (America/Kentucky/Monticello in this case), which automatically handles Daylight Saving Time transitions — no static UTC offset needed. Using the IANA identifier rather than a plain UTC offset means downstream tools (databases, cron jobs, APIs) compute the correct wall-clock time without manual DST adjustments twice a year.

The table below lists ZIP codes in America/Kentucky/Monticello sorted by population. Every ZIP in this time zone is shown below. Each row links to the ZIP's full demographic, housing, and income profile. Time-zone tagging comes from the underlying Census ZIP Code Tabulation Area file cross-referenced with the tz database — the same source used by UNIX, Linux, iOS, and Android for zone data — so the assignments here match what a shipping carrier or phone OS would use for the same five-digit ZIP.
