Current Time in America/Campo_Grande Time Zone

Overview of America/Campo_Grande

America/Campo_Grande is the IANA time zone identifier for the region around Campo Grande, the capital of Mato Grosso do Sul, Brazil. It also applies to other municipalities in the state, including Dourados and Corumbá. The zone is used exclusively in Brazil, and its standard offset is UTC-04:00. Unlike many zones in the Americas, it does not observe daylight saving time, meaning the offset remains constant all year.

Offset and Abbreviation

The offset UTC-04:00 means that when it is noon in Coordinated Universal Time (UTC), it is 08:00 in Campo Grande. The commonly used abbreviation for this zone is AMT (Amazon Time), though this can cause confusion because other Brazilian zones also use similar names. In practice, the offset is the most reliable identifier. This offset is shared by many other zones in the Americas, such as America/Anguilla, America/Antigua, America/Aruba, America/Barbados, America/Blanc-Sablon, America/Boa_Vista, America/Caracas, America/Cuiaba, America/Curacao, America/Dominica, America/Glace_Bay, and America/Goose_Bay. However, note that some of these zones (like America/Glace_Bay and America/Goose_Bay) observe daylight saving time, so their offsets change part of the year. America/Campo_Grande is one of the few in this group that stays constant.

Daylight Saving Time: None

Brazil previously observed daylight saving time in some regions, but it was abolished nationwide in 2019. America/Campo_Grande has not observed DST since then. The zone's offset is UTC-04:00 all year, with no spring-forward or fall-back adjustments. This simplifies scheduling for residents and businesses, as there is no twice-yearly clock change.

Countries and Cities

The only country using America/Campo_Grande is Brazil. Major cities in this zone include Campo Grande (the anchor city), Dourados, Corumbá, and Três Lagoas. All are located in the state of Mato Grosso do Sul, which borders Bolivia and Paraguay to the west. The zone covers an area of about 357,000 square kilometers, with a population of roughly 2.8 million people.

Practical Guidance for Scheduling

When scheduling calls or meetings with someone in America/Campo_Grande, remember that the offset is UTC-04:00. This means it is 1 hour behind New York (UTC-05:00 during standard time, but New York observes DST, so the difference varies). For example, when New York is on Eastern Daylight Time (UTC-04:00), the two zones are the same. When New York is on Eastern Standard Time (UTC-05:00), Campo Grande is 1 hour ahead. For London (UTC+00:00 or UTC+01:00 in summer), Campo Grande is 4 or 5 hours behind. For Tokyo (UTC+09:00), it is 13 hours behind. The lack of DST makes it easier to compute time differences year-round, but always check the current offset of the other zone if it observes DST.

Business Hours Overlap

Typical business hours in Campo Grande are 08:00 to 18:00 (local time). For a company in New York, the overlap is best when New York is on EDT (UTC-04:00), as both zones are the same. During EST (UTC-05:00), Campo Grande is 1 hour ahead, so New York morning (09:00 EST) corresponds to Campo Grande 10:00 AM, offering good overlap. For London, the overlap is limited: London afternoon (14:00 BST) is Campo Grande 10:00 AM, while London morning (09:00 BST) is Campo Grande 05:00 AM (too early). For Tokyo, there is virtually no overlap during business hours, as Tokyo evening (18:00 JST) is Campo Grande 06:00 AM, and Tokyo morning (09:00 JST) is Campo Grande 21:00 (previous day).
