How this service works
Parse, sum and format ISO 8601 durations (PT36H, P1Y2M10DT2H30M), or turn seconds into ISO and clock form.
Output
Returns a JSON object with a 'sum' field containing the aggregated duration in ISO 8601 format plus numeric components (years, months, days, hours, minutes, seconds, totalSeconds), an 'items' array with per-input breakdowns, and a human-readable summary string. When using the 'seconds' input mode, returns the equivalent ISO 8601 string and clock-form decomposition.
Example use cases
Summing project time logs
“I have a list of time entries from our project tracker: PT2H30M, PT1H15M, PT45M, and PT3H. Can you add them all up and give me the total as an ISO 8601 duration and also in plain hours and minutes?”
Converting seconds to readable duration
“Our analytics pipeline gave me a session duration of 93780 seconds — can you convert that to ISO 8601 format and also show it broken down into hours and minutes, carrying full days out separately?”
Parsing a complex ISO duration string
“What does the duration P1Y2M10DT2H30M actually mean in plain terms? Break it down into years, months, days, hours, and minutes for me, and tell me the total in seconds too.”
Technical details
Endpoint
GEThttps://work-time-calc.x402tookit.com/duration?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically parse, sum, or convert ISO 8601 duration strings or raw second counts — especially in payroll, project management, or scheduling contexts where standard duration arithmetic is needed without a full calendar engine. Prefer it over date-diff endpoints when you already have durations and just need to aggregate or reformat them.
Side effects
- Invalid ISO 8601 duration string returns a reasons array with parse error details
- Mixing 'durations' and 'seconds' parameters may yield unexpected results — use one mode at a time
- Very large duration values may produce null for certain fields if overflow occurs
- Missing required 'input' wrapper object returns a 400-level error
- Non-numeric seconds value causes schema validation failure
