Our Mission
Simplifying ISO 8601 Duration Format - We believe that working with time durations shouldn't be complicated. Our free online tool makes it easy to convert between ISO 8601 duration strings (like PT1H30M) and human-readable formats, or generate valid strings from individual time components.
Whether you're a developer working with APIs, an SEO professional implementing structured data, or a data analyst processing time-based information, our tool eliminates the guesswork and potential errors that come with manual duration string creation.

🔢 Individual Fields Mode
Enter specific values for years, months, days, hours, minutes, and seconds using our intuitive form. The tool automatically generates the correct ISO 8601 string, handling all the complex formatting rules for you.
