3. Select a time range on the grid: Use the Select button to switch into selection mode, then drag across the colored timeline to highlight a meeting window in purple. You can drag the center of the selection to move it or use the left and right handles to resize it, which helps when testing whether a work-hour block in Havana also lands inside acceptable hours for the other locations on your grid.

4. Export and share the result: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. These options are useful when you want to send a confirmed meeting slot to a distributed team, create a calendar event that displays correctly in each participant’s local time, or quickly share a Cuba-based schedule with clients and partners.

About Cuba Daylight Time (CDT)

CDT (Cuba Daylight Time, UTC-4) is the daylight saving time abbreviation used in Cuba. It applies to the country’s principal cities, including Havana, Santiago de Cuba, Camagüey, Holguín, and Guantánamo, making it the relevant reference when planning calls, travel, or operations during Cuba’s daylight saving period.

Cuba Daylight Time is set at UTC-4, which places it four hours behind Coordinated Universal Time. This matters for anyone arranging cross-border communication, because the UTC offset is the fixed reference used by calendars, airline systems, and international scheduling tools when converting between Cuba and other regions.

Cuba Daylight Time is the daylight saving counterpart to CST. In practice, that means CDT is the seasonal version used during the daylight saving period, while CST is the standard-time version used outside that period, so the abbreviation changes depending on the part of the year.

Several other abbreviations share the same UTC-4 offset as Cuba Daylight Time, including AMT, AST, AT, BOT, CIDST, CLT, EDT, ET, FKT, GYT, Q, and VET. Shared offset does not always mean the same rules or seasonal behavior, but it is still useful when comparing overlapping business hours or identifying regions that align with Cuba by clock time.

CDT and Daylight Saving Time

CDT (Cuba Daylight Time, UTC-4) is itself a daylight saving time abbreviation rather than a year-round standard time zone label. Its standard counterpart is CST, so when Cuba is observing daylight saving time, schedules, meeting invites, and time-stamped communications should use CDT instead of CST.

Cuba Daylight Time switches to CST when daylight saving time ends, and switches from CST back to CDT when daylight saving time begins again. This distinction is important for recurring meetings, travel itineraries, and shared calendars, because the abbreviation and seasonal offset label change even when the city remains the same.

When working with Cuba Daylight Time, the key practical point is to confirm whether your meeting date falls in the daylight saving period or the standard-time period before sending invitations. That helps avoid confusion for international teams comparing Havana or Santiago de Cuba with other locations, especially when some regions are on daylight saving time and others are not.
