Convert Datetime
Convert any datetime string to ISO 8601, RFC 2822, Unix timestamp, UTC, and local formats.
What is Convert Datetime?
Convert Datetime is a free tool that converts a datetime input into multiple standard formats: ISO 8601, RFC 2822, Unix timestamp, UTC, and local time. It also supports timezone offset display.
How It Works
The tool parses the input datetime string using JavaScript's Date constructor and then formats the result using built-in methods like toISOString(), toUTCString(), toLocaleString(), and getTime().
How to Use
- 1
Enter a date and time
Type or pick a date and time using the date picker. The current time is pre-filled automatically.
- 2
Select source timezone
Choose the timezone the input date/time is in.
- 3
Select target timezone
Pick one or more target timezones to convert the time to.
- 4
View conversions
All timezone-converted equivalents are displayed at once, including UTC offsets and DST status.
