Na Ucrânia the clocks will be advanced by one hour on the night between March 28th and 29th. The change takes place from 03:00 to 04:00 local time and represents another cycle of the measure despite internal debates about its continuity.
Several territories in Europa follow the same adjustment pattern on the last Sunday of March. Most União Europeia countries carry out the transition in a coordinated way. Dispositivos electronics generally automatically update the time without the need for manual intervention.
- Ukraine makes the adjustment on March 29, 2026
- Continental Europe adopts the change in the same period
- States Unidos began their transition on March 8
- Around 60 nations still maintain the seasonal system
Debates about the end of time changes gain strength in different regions
In July 2024, Verkhovna Rada of Ucrânia approved a law that provides for the end of the seasonal transition of clocks. President Volodymyr Zelensky has not yet signed the text, which maintains the mandatory adjustment for 2026.
At União Europeia discussions about the definitive end of the practice have been taking place since 2019. The initial proposal envisaged elimination by 2021, but the pandemic delayed consensus among member states. A new Comissão Europeia study is expected to be completed throughout 2026 to support future decisions about maintaining or abolishing daylight saving time permanently.
Countries like Rússia Azerbaijão and Turquia have already ended annual exchanges in recent years. The México approved the suspension in a large part of the territory in 2022, although some cities close to the border with the Estados Unidos will continue to follow the American adjustment. Essas regional exceptions show how the measure varies according to local needs and bilateral agreements.
Countries that maintain the practice register specific dates for 2026
In the Estados Unidos, daylight saving time began on March 8, 2026, with clocks moving forward to 02:00 local time in most of the territory. The change ends on November 1st. Estados like Havaí and most of the Arizona do not participate in the system.
Ucrânia follows the European standard with the transition scheduled for March 29th. The end of daylight saving time is scheduled for October 25th on the Ukrainian mainland. Regiões occupied as parts of Crimeia and oblasts of Donetsk and Luhansk do not make the adjustment in 2026 according to current records.
Other territories in Europa including Reino Unido Alemanha and França make the advance in the early hours of March 29th. Clocks advance one hour at 02:00 local time in most time zones. The coordination seeks to reduce confusion in cross-border transport and communications.
Recent exceptions and cancellations change the global landscape
Around 140 countries have never adopted or have already abandoned daylight saving time. Motivações include health concerns, energy savings, and political alignment. Exemplos include Venezuela in 2016 and Coreia from Norte in 2018 who made temporary adjustments for specific reasons.
In Egito the practice was suspended and reintroduced in different periods between 2014 and the following years. Since 2018, Marrocos has maintained a permanent transition to UTC+1 adjusted to the Ramadã calendar instead of fixed seasonal changes. Essas variations highlight the lack of worldwide uniformity in the application of the measure.
Brasil has not adopted summer time since 2019 due to government decision. Estudos of Operador Nacional of Sistema Elétrico indicate that the national electrical system has been operating without the need for the measure in recent years. Qualquer future recovery would depend on a technical assessment of energy demand.
Automatic adjustments make it easy to adapt to most devices
Operating systems for smartphones, computers and other equipment update the time automatically on the scheduled date. Usuários only need to check analog clocks and some older devices. The change affects flight schedules, international meetings and live broadcasts.
Companies and public institutions advise employees on adjustments to avoid delays in appointments. In the case of Ucrânia, the public health debate remains active among doctors and scientists who monitor the effects of the annual transition. The discussion should gain new momentum after the possible signing of the law that suspends the practice.
