This Sunday, November 1, 2026, Cuba finds itself one hour ahead of Miami after the Florida city set back its clocks while the island continued with daylight saving time. From this morning, when it is 3:00 a.m. in Miami, it's already 4:00 a.m. in Havana.
The time adjustment occurred at 2:00 a.m. Eastern Time in the United States, when clocks were turned back to 1:00 a.m., in accordance with the National Institute of Standards and Technology (NIST) schedule. Consequently, Miami transitioned to UTC−5, whereas Cuba remains on UTC−4.
This time difference also impacts other cities within the Eastern Time Zone, such as New York and Washington, D.C. For those arranging calls, appointments, or travel between Cuba and Miami, it is now crucial to specify which time zone is being referred to.
Why Didn’t Cuba Change Its Clocks?
On October 24, the Ministry of Energy and Mines along with the Ministry of Labor and Social Security announced that the island will maintain daylight saving time until November 7, 2027. Their joint statement postponed the shift back to standard time that was originally scheduled for this Sunday.
The regime linked this decision to the ongoing electricity crisis. Officials estimated that keeping daylight saving time would prevent an increase of 126 megawatts in demand during peak evening hours: 76 MW from reduced use of artificial lighting and 50 MW from better utilization of solar generation during this period.
Because sunrise occurs later under the current timing, starting November 1, 2026, through March 14, 2027, school and work start times have been delayed by 30 minutes.
When Will the Time Difference End?
According to the current schedule, Miami will move its clocks forward again on March 14, 2027, the second Sunday in March. Following this adjustment, Cuba and Miami will both be aligned at UTC−4 once more.
It is recommended to verify clocks and device alarms in Cuba: if the system retains the previous schedule before the announcement, it might apply an outdated time change. The reference to maintain on the island should be UTC−4.
Historical Time Differences
An image circulated on social media accurately reflects the 4:00 a.m. time in Havana compared to 3:00 a.m. in Miami but incorrectly claims that this time difference hasn't occurred since 2006.
Historical records from the IANA time zone database show that the United States ended daylight saving time on November 6, 2011, while Cuba extended it until November 13. During that week, Havana was also one hour ahead of Miami.
The 2006 reference pertains to another event: Cuba continuously maintained daylight saving time from March 2004 until October 2006. In subsequent years, additional discrepancies occurred with the United States when daylight saving schedules didn't match.
Understanding Cuba's Time Zone Changes
Why is Cuba currently one hour ahead of Miami?
Cuba is one hour ahead of Miami because Miami shifted to standard time, moving to UTC−5, while Cuba remained on daylight saving time at UTC−4.
When will Cuba and Miami have the same time again?
Cuba and Miami will be on the same time again starting March 14, 2027, when Miami moves its clocks forward to match Cuba at UTC−4.
What are the benefits of maintaining daylight saving time in Cuba?
The Cuban government believes that maintaining daylight saving time helps reduce electricity demand during peak hours by decreasing the need for artificial lighting and optimizing solar energy usage.
