## When to prefer this

Choose this endpoint when you need a quick, accurate temporal difference calculation that includes both calendar and business day breakdowns, without standing up your own date math logic. Especially useful in scheduling, invoicing, SLA tracking, or any workflow where business days (excluding weekends) matter alongside raw calendar units.

## Known failure modes

- Invalid date format provided — returns a 400 error with a format hint
- End date is before start date — may return a negative value or error
- Non-existent dates (e.g. February 30) cause a 422 validation error
- Missing required start or end date fields — returns a 400 bad request
