Missouri does actually observe daylight saving time—the only two U.S. states that do not are Arizona and Hawaii. The reason these states skip daylight saving time is straightforward: it’s about their climate and geography, which make extended daylight hours either unnecessary or undesirable.
States Skipping Daylight Saving
- Arizona: The state opted out because it gets intense sunlight and very hot temperatures for much of the year. Avoiding daylight saving time helps keep evenings cooler by matching sunset to cooler hours and helps residents and workers avoid outdoor activity during the heat of late evening.
- Hawaii: Located close to the equator, Hawaii experiences roughly the same amount of daylight year-round. Since sunrise and sunset times don’t change much seasonally, there’s no practical benefit to shifting clocks for daylight saving time.
Why People Think Missouri Doesn’t Observe DST
Missouri does observe daylight saving time in accordance with federal law and changes clocks in spring and autumn like most other states. There is periodic confusion because some states propose legislation to opt out, and there may be misunderstandings due to changing rules or bills, but as of now, Missouri still participates in daylight saving time.
Summary Table
| State | Observes DST? | Reason for Non-Observance |
|---|---|---|
| Arizona | No | Hot climate, energy saving |
| Hawaii | No | Consistent daylight, equatorial |
| Missouri | Yes | N/A |
Missouri’s inclusion in this conversation is a common misconception—only Arizona and Hawaii truly skip daylight saving time due to climate and geography.

What is your source. Missouri always observes the time changes.

Who wrote this BS? Missouri does in fact observe Daylight Savings Time. Arizona and parts of Indiana are the states which do not observe Daylight Savings Time. Get your facts straight!
