RFC 2822 Converter

Turn Any Date and Time Into RFC 2822 Format

What this tool does (and why you might care)

Ever tried working with email headers or syncing times across servers and wondered what that oddly specific timestamp format was? That’s RFC 2822—used in email metadata, HTTP dates, and other places where a standardized timestamp is needed.

This time-conversion calculator lets you take any date and time in a major global timezone and instantly convert it into the RFC 2822 format. That means no more searching for syntax or guessing how to write “Tue, 11 Jun 2025 13:45:00 -0400” the right way.

Set your time, pick a zone, get your result

What you enter

You’ll start by plugging in the date and time you want to convert. Use the familiar date and time pickers—it’s all built-in and feels like setting a calendar event. Then, from a dropdown menu, pick the timezone that applies to that datetime.

Options include popular choices like Eastern, Central, Pacific, London, Berlin, Tokyo, and Sydney. It also includes UTC if you’re working on something that needs universal timing.

One click gives you a perfectly formatted timestamp

Once everything’s filled in, hit the “Convert to RFC 2822” button. The formatted result appears instantly in the output box below. You’ll see something like:

Wed, 11 Jun 2025 10:30:00 +0000

That’s the standard format used in email headers and HTTP protocols. Copy it, paste it, done.

Extra touches that make it smoother to use

Live clock with adjustable format

You’ll notice a live clock ticking away at the bottom—it shows your current system time in either 12-hour or 24-hour format. Want to switch? Just click the “12 Hour” or “24 Hour” button to toggle it. It doesn’t affect the conversion itself, but it’s a nice detail if you’re comparing times on the fly.

Timezone smarts baked in

The converter does more than just shift hours. It checks whether daylight saving time applies based on the date and location you’ve selected. So if you pick “America/New_York” on a summer date, it’ll correctly label the result as EDT instead of EST.

It also includes the proper numeric timezone offset—so something like “+0530” for India or “-0700” for Pacific Daylight Time.

Quick autofill to start with current time

When the page loads, the time and date fields auto-populate with the current moment. That’s handy if you just need to convert right now into RFC 2822 and move on with your day.

Running into trouble? Here’s what to check

Why your result might be blank

If you click “Convert” and nothing appears, double-check that you’ve entered both a time and a date. The converter needs both to do its job, and it’ll gently nudge you with an alert if either is missing.

Why the format might look “off”

The output won’t spell out the timezone abbreviation (like “EDT” or “PST”) in the result—it uses the numeric offset instead. That’s exactly how RFC 2822 is supposed to work. The abbreviation you see in the interface helps you double-check what zone you’re working in.

Keep your timestamps clear, consistent, and RFC-ready

Whether you’re debugging email issues, setting headers for a server, or just making sure a scheduled message hits the right time, this converter saves you the mental math. No time math. No format guesswork. Just a clean, standards-friendly timestamp when you need it.
