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 (ISO 8601) in the original timezone accounting for DST transitions; for 'diff' operations, the numeric difference between the two datetimes expressed in a meaningful unit (e.g. total seconds, minutes, hours, or days).
Example use cases
Contract deadline calculation
“My contract starts on April 1, 2025 at noon in London — what is the exact date and time 90 days later, using calendar days so DST is handled correctly?”
Cross-timezone elapsed time
“How many hours are there between January 15, 2025 at 8am in America/Los_Angeles and January 16, 2025 at 6pm in Europe/Berlin?”
Countdown to event
“I need to subtract 2 weeks from my event date of December 25, 2025 at 10am in Asia/Tokyo — what datetime does that land on?”
Technical details
Endpoint
POSThttps://api.agishub.com/paid/date-calculateWhen to prefer
Choose this endpoint when you need reliable, DST-aware calendar date arithmetic or cross-timezone datetime differencing. It handles the edge cases of daylight saving transitions correctly (days are calendar-based, not always 24-hour periods) and accepts natural language datetimes alongside ISO 8601 strings. Prefer it over client-side date math when DST correctness, cross-timezone accuracy, or auditability matter.
Side effects
- Invalid or unrecognizable datetime string — returns error if natural language cannot be parsed
- Unknown IANA timezone identifier — returns error with message about unrecognized timezone
- Missing required operation parameters (e.g. 'add' without amount/unit, 'diff' without to_datetime) — returns validation error
- Out-of-range or malformed amount values — may return error or unexpected result
- Payment failure or insufficient balance — HTTP 402 response requiring x402 payment
