only observed that year as Brazil abolished DST altogether in 2019. Time changes were almost always done at midnight. The time was advanced from 00:00 to 01:00 on the DST starting date and reduced from 00:00 on the ending date to 23:00 of the previous day. Exceptions were the first DST starting time in 1931 (11:00) and the ending times in 1950 and 1966 (01:00). Regional application Until 1988, in every year that DST was observed it applied to whole country. In 1963 the Southeast region started DST earlier than the rest of the country. From 1988, DST was typically limited to the South, Southeast and Central-West regions, and was occasionally extended to some other states such as Bahia and Tocantins. In 2000, DST was extended to all states in the Northeast region but was quickly canceled in most of them due to strong local opposition.
