How this service works
Add days or business days to a date - calendar or weekday offset from a start date, returns the resulting date and weekday
Output
A JSON object containing the original start date, the computed result date (YYYY-MM-DD), the result weekday name, the number of calendar days added, the number of business days added, an optional note with caveats, and the UTC timestamp when the check was run.
Example use cases
Project deadline calculation
“Our project kicks off on 2025-07-14 — what's the exact date 20 business days later, and what day of the week is it?”
Contract net-30 due date
“If an invoice is dated 2025-08-01, what calendar date is exactly 30 days later and what weekday does it fall on?”
Regulatory filing countdown
“I need to file a response 15 business days after receiving notice on 2025-09-10 — what date does that work out to?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/calc/date-add?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, reliable date offset calculation — either calendar days or business/weekday days — and want the result weekday returned in the same call. It is ideal for scheduling, deadline computation, and SLA calculations where weekend-skipping matters. Prefer it over manual date math or general-purpose date libraries when you need a hosted, pay-per-use API with no setup.
Side effects
- Missing required 'from' query parameter returns an error
- Invalid date format (not YYYY-MM-DD) may return a parsing error
- Non-numeric or malformed days/business_days values cause request failure
- Extremely large offsets may produce unexpected or out-of-range dates
- Network or payment (x402) failure prevents response
