KST to BRT Conversion Guide

What is KST to BRT Conversion?

KST to BRT conversion helps you translate time between Korea Standard Time and Brasília Time. KST is UTC+9 and remains constant year-round as South Korea does not observe daylight saving time. BRT is UTC-3 and also remains constant as Brazil abolished daylight saving time in 2019. The time difference is always 12 hours, with Korea being ahead of Brazil.

Time Zone Information

Korea Standard Time (KST): Used throughout South Korea including all major cities. Always UTC+9 with no daylight saving time since 1988.

Brasília Time (BRT): Used throughout most of Brazil including major metropolitan areas. Always UTC-3 with no daylight saving time since 2019.

Time Difference: KST is consistently 12 hours ahead of BRT throughout the year.

Time Zone Stability

Korean Consistency: South Korea discontinued daylight saving time after testing it briefly during the 1988 Seoul Olympics

Brazilian Uniformity: Brazil abolished daylight saving time in 2019 after studies showed minimal energy savings

Fixed Difference: The 12-hour time difference never changes, making conversion straightforward
