Current Time in America/Mazatlan Time Zone

Geographic Scope and Usage

America/Mazatlan applies to the Mexican states of Baja California Sur, Sinaloa, Sonora (excluding the border municipalities that follow America/Hermosillo), and the western portion of Nayarit. Major cities include Mazatlan, La Paz, Los Cabos, Hermosillo (though Hermosillo city itself uses America/Hermosillo, which shares the same offset), Culiacan, and Tepic. The zone covers the Baja California peninsula and the mainland Pacific coast, from the US border down to the Nayarit-Jalisco border. It is the standard time for the region, used by government, businesses, and daily life.

Offset and Abbreviation

The standard offset is UTC-07:00, which means when it is noon UTC, it is 5:00 AM in Mazatlan. The abbreviation MST is commonly used, standing for Mountain Standard Time. However, unlike the US MST, this zone does not observe daylight saving, so MST is used all year. The offset is 2 hours behind Eastern Standard Time (UTC-05:00) and 1 hour ahead of Pacific Standard Time (UTC-08:00).

Daylight Saving: None

America/Mazatlan does not observe daylight saving time. The offset remains constant at UTC-07:00 throughout the year. This means there is no spring-forward or fall-back clock change. The region decided to stay on standard time permanently, aligning with the federal government's 2022 decision to end seasonal clock changes in most of Mexico. As a result, the time in Mazatlan is the same all year, simplifying scheduling for residents and visitors.

Comparison with Other Zones at UTC-07:00

Several other IANA zones share the same standard offset of UTC-07:00, but many of them observe daylight saving. For example, America/Denver (US Mountain Time) switches to UTC-06:00 in summer, while America/Phoenix (Arizona) stays on UTC-07:00 year-round like Mazatlan. Other zones at UTC-07:00 that do not observe DST include America/Creston (Canada, British Columbia) and America/Dawson (Canada, Yukon). America/Hermosillo is a separate zone for the city of Hermosillo and some border areas, but it also uses UTC-07:00 without DST. When scheduling with US cities like Denver, you must account for DST: during US summer, Denver is UTC-06:00 (MDT), so Mazatlan is 1 hour behind Denver; in winter, both are UTC-07:00 (MST), so they are the same.

Practical Guidance for Business and Calls

For scheduling calls between America/Mazatlan and other regions, note the following: With US Eastern Time (UTC-05:00 standard, UTC-04:00 DST), Mazatlan is 2 hours behind in winter and 3 hours behind in summer. With US Pacific Time (UTC-08:00 standard, UTC-07:00 DST), Mazatlan is 1 hour ahead in winter and the same in summer. With Europe (e.g., London UTC+00:00 standard, UTC+01:00 DST), Mazatlan is 7 hours behind in winter and 8 hours behind in summer. With Japan (UTC+09:00, no DST), Mazatlan is 16 hours behind. Always confirm the current DST status of the other party's zone. Because Mazatlan does not change clocks, the time difference with DST-observing zones shifts twice a year.

History and Background

Mexico has used several time zones historically. The America/Mazatlan zone was created to represent the Pacific coast region that chose not to follow the US DST pattern. In 2022, Mexico eliminated DST for most of the country, making this zone permanent. Previously, the zone had observed DST as part of the US-aligned schedule, but now it remains on standard time year-round. The zone name comes from the city of Mazatlan, a major port and tourist destination in Sinaloa.
