What time is it in area code 931?

Area code 931 covers 2 time zones – Eastern and Central – so the code alone does not tell you what time it is for the person you are calling. Which zone applies depends on where in Tennessee the number was assigned, and nothing in the number itself says which. Clocks go forward on 8 March 2026 and back on 1 November 2026. The code's largest rate centers are CLARKSVL, COOKEVILLE and COLUMBIA, as NANPA abbreviates them. Other codes keeping the same time in Tennessee: 423 and 729.

Eastern time · America/New_York – EST UTC−5 · EDT UTC−4 in summer
Central time · America/Chicago – CST UTC−6 · CDT UTC−5 in summer

Clocks run in your browser from the IANA time zone database, so they stay right between page rebuilds. This code spans more than one zone: both clocks are shown because the number alone does not say which applies.

Questions about 931 and time

What time is it in area code 931?

931 spans Eastern and Central, so there is no single answer – the clock above shows all 2.

Does area code 931 observe daylight saving time?

Yes. Clocks go forward on 8 March 2026 and back on 1 November 2026.

How do I know which time zone a 931 number is in?

You cannot tell from the number. The zone follows the rate center the number was assigned to, which is not encoded in the digits. Ask, or go by the town if you know it.

Why does a 931 caller reach me at an odd hour?

Two common reasons. Either the clocks differ by more than you expected – the offset changes twice a year and not everywhere on the same date – or the caller ID is not really 931 at all. Spam callers fake a local-looking number, so the displayed code says nothing about where the call came from.
