MST to CST Time Zone Converter
This converts US Mountain Time (Denver, Salt Lake City — locals say MT) to US Central Time (Chicago, locals say CT). Central is 1 hour ahead of Mountain, and since both zones share the same daylight saving calendar, that gap never changes all year. The converter still checks the exact date for you.

Daylight saving is applied automatically for the date you pick. Labels like PST/EST name the zone (Pacific/Eastern); the real abbreviation shifts to PDT/EDT during daylight saving, and gmt here means London (GMT in winter, BST in summer) while utc stays fixed.
The time difference
US Central Time is 1 hour ahead of US Mountain Time, and that gap holds all year. Both zones follow the same US daylight saving calendar, so they move together and the difference never drifts. Add an hour to a Mountain clock and you have the Central time — it's the smallest, simplest jump between two neighboring US zones.
A worked example
Take 9:00 AM in Denver. On January 15, 2026 that's 10:00 AM in Chicago. On July 15, 2026 it's still 10:00 AM — the same clock result, because the two zones spring forward and fall back on the same dates. The 1-hour gap is one you can rely on any day of the year.
Daylight saving & the abbreviation caveat
The slug says MST and CST, the standard-time names, but both zones shift to daylight time in the warm months — MDT and CDT — which is why locals just say "MT" and "CT." US clocks spring forward on March 8, 2026 and fall back on November 1, 2026. Because both sides switch on the same dates, the gap stays a clean 1 hour straight through the changeovers. The converter sorts out the right labels for the date you pick, so nothing looks off.
When you'll use it
Handy for coordinating with a Chicago, Dallas, or Houston team, catching a Central-time game or broadcast, or timing a call that's just one hour apart. It's the mildest of the US cross-zone conversions, so it mostly comes up as a quick sanity check before a meeting.
Frequently asked questions
How many hours ahead is Central Time?
Central is 1 hour ahead of Mountain, every day of the year. When it's 9:00 AM in Denver, it's 10:00 AM in Chicago.
Does the 1-hour gap ever change?
No. Mountain and Central spring forward and fall back on the same dates, so the 1-hour gap holds steady through winter and summer alike.
What about Arizona?
Arizona stays on MST year-round and doesn't spring forward, so in summer it's 2 hours behind Central. This converter uses standard US Mountain (Denver) rules, which keep a steady 1-hour gap.
