  • The state of Quintana Roo has switched to GMT -5 year-round
  • This means no Daylight Saving Time (DST) changes are observed
  • It's the same as Eastern Standard Time (EST) or Central Daylight Time (CDT) year-round
    • Avoid using US time zones such as EST or CDT because US times zones follow DST
  • Selecting "Cancun" on a device runs some risk of setting your time wrong, since many systems have not updated to the new time zone parameters
  • Up-to-date Apple devices do set the time correctly using "Cancun"
  • Chetumal is the capitol of Quintana Roo and systems that include it (Windows 10) should set the time correctly
  • Bogota works correctly as it's also GMT -5 and does not observe DST

Sunrise and sunset are fairly consistent year-round

Ignore the DST changes in the above graphic, as Daylight Saving Time no longer applies.
  • Due to the tropical location, day length varies by less than 2 1/2 hours over the course of the year
