Puerto Rico Time Zone: All You Need To Know (2024)

Are you planning a trip to Puerto Rico or need to coordinate with someone on the island? Knowing the correct time zone is essential. Puerto Rico observes Atlantic Standard Time (AST) year-round, which is four hours behind Coordinated Universal Time (UTC-4). This guide provides everything you need to know about Puerto Rico's time zone, including comparisons to other time zones, daylight saving time practices, and tips for avoiding confusion.

Understanding Atlantic Standard Time (AST)

Atlantic Standard Time (AST) is used in several regions of the Caribbean and North America. It's important to understand its relationship to other time zones for easy conversion.

AST vs. EST and EDT

• AST vs. EST: During Eastern Standard Time (EST), which is observed from November to March, AST is one hour ahead. So, if it's 2:00 PM EST, it's 3:00 PM AST.
• AST vs. EDT: During Eastern Daylight Time (EDT), which is observed from March to November, AST is the same as EDT. So, if it's 2:00 PM EDT, it's also 2:00 PM AST.

Other Regions Using AST

Besides Puerto Rico, AST is also used in:

• U.S. Virgin Islands
• Parts of Canada (New Brunswick, Nova Scotia, Prince Edward Island)
• Bermuda

Does Puerto Rico Observe Daylight Saving Time?

Puerto Rico does not observe Daylight Saving Time (DST). This means the island remains on AST year-round. This can simplify things, as you don't need to worry about changing your clocks twice a year.

Reasons for Not Observing DST

The decision not to observe DST is primarily due to Puerto Rico's proximity to the equator. The length of daylight hours varies less throughout the year compared to regions farther from the equator. Therefore, the energy savings and other benefits typically associated with DST are minimal.

Historical Context

Puerto Rico briefly experimented with DST during World War II to conserve energy but later abandoned the practice. Since then, the island has remained on AST year-round.

Converting to Puerto Rico Time

To easily convert to Puerto Rico time, consider these scenarios:

Converting from EST

During EST (November to March), add one hour to the EST time to get the equivalent time in AST. For example:

• 10:00 AM EST = 11:00 AM AST

Converting from EDT

During EDT (March to November), the time is the same as AST. For example: — 1997 BMW Z3 Convertible: Review, Specs, And Value
