Problem

Calendar math gets messy as soon as the clock matters.

A simple due-date calculation can become a support bug when it crosses weekends, holidays, business-hour windows, or time zones. A shared API keeps those deadlines consistent across tools.

When to use it

  • You need support, logistics, legal, or admin deadlines with business-hour rules.
  • You need one repeatable deadline calculation before wiring the logic into another tool.
  • You need repeatable US federal holiday-aware due dates across tools.
  • You want to avoid copying deadline logic into every workflow.

Non-goals

  • Not a full workforce-scheduling or shift-planning system.
  • Not international holiday coverage beyond the calendars the API exposes.
  • Not a ticket, logistics, or CRM product by itself.
