Read before relying

Context matters.

  • Calendar-day, week, month and year operations use date-only Gregorian arithmetic; daylight-saving changes do not alter the result.
  • Month-end policy is ignored unless the selected unit is months or years.

Source & calculation QA reviewed

The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.

How this calculation works

A visible path from input to answer.

Measure date spans, add or subtract calendar units, count business days and compare date-times with explicit inclusion, holiday, time-zone and DST rules. The page keeps the calculation scope and its limits beside the result so the output can be checked, copied or revisited.

Calculation flow
  1. Read the record. The calculator uses What do you want to calculate?, From date, To date, Direction and Starting date and 21 additional fields supplied in the form.
  2. Apply the scope. It applies the Global Gregorian date arithmetic and IANA time zones; optional U.S. federal holiday planning calendar reference and the explicit date, unit and counting conventions shown in the result.
  3. Expose the checkpoints. Intermediate rows, warnings and timeline events stay visible; the emphasized row identifies the primary checkpoint when one exists.
Illustrative default example 30 days

Standard elapsed-date counting excludes the start boundary. The result is shown as an absolute span.

Assumptions and scope

Calculation purpose: Measure date spans, add or subtract calendar units, count business days and compare date-times with explicit inclusion, holiday, time-zone and DST rules. This is a high-sensitivity reference output; the linked authority or qualified professional controls the final decision.

Boundary behavior

Calendar inputs use plain year-month-day semantics. Leap days, month ends, date-pair order and unsupported dates are checked before the result is shown.
