The toUTCString()
method of Date
instances returns a string representing this date in the RFC 7231 format, with negative years allowed. The timezone is always UTC. toGMTString()
is an alias of this method.
const event = new Date("14 Jun 2017 00:00:00 PDT");
console.log(event.toUTCString());
// Expected output: "Wed, 14 Jun 2017 07:00:00 GMT"
Syntax Parameters
None.
Return valueA string representing the given date using the UTC time zone (see description for the format). Returns "Invalid Date"

is a string in the form Www, dd Mmm yyyy HH:mm:ss GMT
, where:
Www
Day of week, as three letters (e.g., Sun
, Mon
) dd
Day of month, as two digits with leading zero if required Mmm
Month, as three letters (e.g., Jan
, Feb
) yyyy
Year, as four or more digits with leading zeroes if required HH
Hour, as two digits with leading zero if required mm
Minute, as two digits with leading zero if required ss

JavaScript's Date
API was inspired by Java's java.util.Date
library (while the latter had become de facto legacy since Java 1.1 in 1997). In particular, the Java Date
class had a method called toGMTString
â which was poorly named, because the Greenwich Mean Time is not equivalent to the Coordinated Universal Time, while JavaScript dates always operate by UTC time. For web compatibility reasons, toGMTString
remains as an alias to toUTCString
, and they refer to the exact same function object. This means:
Date.prototype.toGMTString.name === "toUTCString";
Examples Using toUTCString()
const d = new Date(0);
console.log(d.toUTCString()); // 'Thu, 01 Jan 1970 00:00:00 GMT'
