Elapsed time between instants
Calculate precise elapsed time between ISO timestamps, honoring explicit offsets.
The end instant minus the start instant gives elapsed milliseconds, which are converted to total seconds and duration components. A day component means a fixed 24 hours, independent of calendar dates or daylight-saving boundaries.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
Start ISO timestamp: 2024-01-01T00:00:00Z End ISO timestamp: 2024-01-02T01:30:00Z
Example result
{
"totalSeconds": 91800,
"days": 1,
"hours": 1,
"minutes": 30,
"seconds": 0
}Limitations and details
The end must not precede the start, and both timestamps need seconds and Z or an explicit offset; inputs support up to millisecond precision.
