LetterStream Timezone
Our facilities are located in Arizona, which is in the Mountain Time Zone (MT), but we have a unique twist!
Key Details:
- Standard Time: Arizona follows Mountain Standard Time (MST) year-round, which is UTC−7.
- No Daylight Saving Time: However, most of Arizona (including LetterStream locations) does not observe Daylight Saving Time (DST). So, unlike other Mountain Time areas, we do not switch to MDT (UTC−6) in the summer.
