How this service works
Reconstruct positive/negative working-day offsets and inclusive working-day counts from an explicit calendar.
Output
Returns the reconstructed WORKDAY date (the date that falls N working days from start) and/or the reconstructed NETWORKDAYS count (the inclusive count of working days between start and end), computed from the provided weekend bitmask and holiday list. If a claim object is provided, the response can be compared against the submitted claim values for validation.
Example use cases
Audit Excel NETWORKDAYS formula output
“I have a spreadsheet that claims there are 65 working days between 2025-03-01 and 2025-06-01, using a standard Monday-Friday week (mask '0000011') with holidays on 2025-04-18 and 2025-05-26. Can you reconstruct the correct NETWORKDAYS count and tell me if 65 is right?”
Verify WORKDAY offset for contract deadline
“A contract starts on 2025-02-03 and the deadline is supposed to be 45 working days later. The weekend mask is '0000011' and holidays are 2025-02-17 and 2025-04-18. Can you reconstruct what the actual deadline date should be and check if the claimed date of 2025-04-07 is correct?”
Custom weekend mask payroll calculation
“Our team works Sunday through Thursday so the weekend mask is '1000001'. Starting 2025-01-05 through 2025-04-05, with holidays on 2025-01-13 and 2025-03-30, reconstruct how many net working days fall in that range and what date is 20 working days from 2025-01-05.”

Endpoint
POSThttps://detect.halowerk.com/v1/F-TD2000-DOCUMENTS-05/xlsx-explicit-weekmask-holiday-workday-networkday-calendar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to reconstruct or validate spreadsheet-compatible WORKDAY and NETWORKDAYS calculations against an explicit, fully-specified calendar — including custom weekend patterns (non-standard workweeks) and arbitrary holiday lists. Prefer it over generic date-math libraries when you need Excel/Google Sheets formula parity, auditability of claimed results, or support for non-Monday-Friday weekends.
Side effects
- Invalid date format (not YYYY-MM-DD) returns a validation error
- Weekend mask not exactly 7 characters of 0/1 returns a schema error
- Offset outside the range -3660 to 3660 is rejected
- More than 256 holidays in the array causes rejection
- Missing required fields (start, end, weekend, holidays, offset) return 400-level errors
- Ambiguous or impossible calendar configurations may return unexpected results
