EDT to GMT Conversion Guide

What is EDT to GMT Conversion?

EDT to GMT conversion helps you translate time between Eastern Daylight Time and Greenwich Mean Time zones. EDT is UTC-4 and is used during summer months in the eastern United States and Canada. GMT is UTC+0 and serves as the reference point for world time zones. The time difference is 4 hours, with GMT being ahead of EDT.

Time Zone Information

Eastern Daylight Time (EDT): Used during summer months (March to November) in New York, Toronto, Montreal, and Miami. UTC-4 with daylight saving time adjustments.

Greenwich Mean Time (GMT): Used during winter months in the UK and several African countries. UTC+0 and serves as the global time reference point.

Time Difference: GMT is consistently 4 hours ahead of EDT. When EDT switches to EST in winter, the difference becomes 5 hours.

Daylight Saving Time Impact

Eastern Time Zone: Observes EDT (UTC-4) from second Sunday in March to first Sunday in November, then switches to EST (UTC-5)

UK Time Zone: Uses GMT (UTC+0) during winter and BST (UTC+1) during summer months

Seasonal Differences: EDT to GMT: +4 hours | EST to GMT: +5 hours | EDT to BST: +5 hours | EST to BST: +6 hours

EDT to GMT Time Converter

If you've ever tried setting up a meeting between New York and London, you know just how tricky time zone math can get. This tool makes it effortless to switch between Eastern Daylight Time (EDT) and Greenwich Mean Time (GMT). Here's a quick look at where these time zones apply, side by side:

EDT (UTC-4)	GMT (UTC+0)
🇺🇸 United States 🇨🇦 Canada 🇧🇸 Bahamas 🇹🇨 Turks and Caicos Islands	🇬🇧 United Kingdom 🇮🇪 Ireland 🇵🇹 Portugal 🇮🇸 Iceland 🇬🇲 The Gambia 🇸🇱 Sierra Leone 🇱🇷 Liberia 🇬🇭 Ghana 🇬🇳 Guinea 🇬🇼 Guinea-Bissau 🇸🇳 Senegal 🇲🇷 Mauritania 🇧🇫 Burkina Faso 🇨🇮 Côte d’Ivoire 🇹🇬 Togo 🇲🇱 Mali 🇳🇪 Niger 🇸🇹 São Tomé and Príncipe

Why This Tool Exists

Juggling time zones manually is asking for a mistake. Whether you're trying to catch a live broadcast, plan a Zoom call with someone in another part of the world, or schedule international deliveries, small timing errors can snowball into missed meetings or confusion. This converter gives you a fast, no-headache way to see the time in both zones at once.

Simple Steps to Convert Any Time

1. Pick your starting zone

By default, it assumes you're starting with Eastern Daylight Time. If you're in the UK or one of the GMT countries, you can swap the zones with the ⇄ button.

2. Set the time and date

Choose the exact day and hour you want to convert. You can type it in or click the ⌚ button to auto-fill the current time.

3. Let the tool handle daylight saving

The converter checks if daylight saving is in effect on your chosen date, adjusting the offset for you. This means it accounts for both EDT switching to EST and GMT becoming BST in summer months.

4. See your results instantly

As long as “Auto Convert” is checked, the conversion happens as soon as you change a time or zone. You’ll see the converted time, date, time difference, and both UTC offsets in one view.

Make the Most of the Features

Switch formats with a tap

If you prefer military time or are working in 24-hour systems, you can switch between 12-hour and 24-hour formats using the format toggle.

Live time display

At the bottom, you’ll always see the current live time in both zones. It updates every second and automatically reflects DST changes.

Fine-tune your preferences

Auto Convert: Turns on instant updates as you type or change the date.
Daylight Saving Aware: Ensures the conversion uses the right seasonal offset.
Show UTC Offset: Displays UTC values to give extra context.

Need to reverse it?

Click the swap button to instantly flip which zone is the input and which is the output. The labels and values update automatically to reflect the change.

Example: Planning Between the US and UK

Let’s say you’re in Canada (🇨🇦) and your partner is in Ireland (🇮🇪). You want to set a weekly video chat. You pick 7:00 PM in EDT. Instantly, the tool shows that it’s 11:00 PM GMT. That helps you find a time that works for both without back-and-forth confusion. Whether it's The Bahamas to Portugal or New York to London, this tool handles the logic so you don’t have to.

Time Zones Don't Have to Be a Puzzle Anymore

This converter isn’t just handy, it’s reliable. With support for daylight saving shifts and real-time updates, it saves you from timezone math and lets you focus on the actual planning. Whether you're coordinating business across continents or catching up with a friend, it keeps you grounded in the right time, every time.
