How to Use This Tool
We designed this tool to be both beautiful and simple. At the top, the main display shows you the exact time in San Juan. Below, in this "frosted glass" panel, you can find your own local time, the live difference, and tools to switch between 12-hour and 24-hour formats.
The Unchanging Rhythm: A Deep Dive into Atlantic Standard Time
The most important detail for any traveler or professional is that Puerto Rico does not observe Daylight Saving Time (DST). The island remains on Atlantic Standard Time (AST), which is UTC-4, all year long. This creates a fascinating and often confusing relationship with the US East Coast.
- During Summer: When cities like New York and Miami "spring forward" to Eastern Daylight Time (EDT), which is also UTC-4, they share the exact same time as San Juan.
- During Winter: When those same cities "fall back" to Eastern Standard Time (EST), or UTC-5, San Juan is suddenly one hour ahead.
This tool eliminates that guesswork, always showing you the correct, live time difference no matter the season.

Behind the 'Isla Vibrante' Design
The look and feel of this page are a tribute to Puerto Rico itself. The vibrant, warm gradient is inspired by a Caribbean sunrise and sunset. The "frosted glass" effect of the panel mimics the sea glass found on the island's shores. The lively colors—ocean blue, coral pink, and sunny yellow—are all reflections of the island's energy, culture, and natural beauty. It’s designed to be more than a tool; it's a small dose of island life.
