How this service works
Timezone-aware date arithmetic: add or subtract a duration to a datetime (days are calendar-based and DST-safe; hours and minutes are absolute), or compute the difference between two datetimes that may be in different zones.
Output
A JSON object containing the computed result: for 'add' operations, the resulting datetime string in the specified timezone; for 'diff' operations, the numeric difference between the two datetimes in the relevant unit, both adjusted for DST and cross-timezone offsets.
Example use cases
Contract deadline calculation
“I signed a contract on January 10, 2025 in America/Chicago time. What is the exact date 180 calendar days later, accounting for daylight saving time?”
Cross-timezone meeting gap check
“How many hours are there between a meeting starting on March 28, 2025 at 10:00am in Europe/London and another event on March 29, 2025 at 8:00am in Asia/Tokyo?”
Subscription renewal countdown
“My subscription started on November 1, 2024 at midnight in Australia/Sydney. What date is exactly 1 year later, accounting for any DST changes?”
Technical details
Endpoint
GEThttps://api.agishub.com/v1/date-calculateWhen to prefer
Choose this endpoint when you need precise, DST-aware calendar arithmetic — especially when crossing daylight saving boundaries or computing differences between datetimes in different IANA timezones. It distinguishes between calendar-based days (which respect DST) and absolute hours/minutes, making it more reliable than naive date math. Prefer it over general-purpose LLMs for date arithmetic to avoid hallucination errors in timezone-sensitive calculations.
Side effects
- Invalid or unrecognized IANA timezone identifier returns an error
- Malformed or ambiguous datetime string that cannot be parsed fails with a parsing error
- Missing required 'operation' fields (e.g. amount/unit for 'add', to_datetime for 'diff') return a validation error
- Providing an out-of-range amount (extremely large durations) may produce unexpected results
- Network or service unavailability returns a non-200 HTTP error
