Measure an elapsed interval
This calculator starts with two known dates: dispatch and delivery or a proposed due date. It excludes the dispatch date and includes the end date when that date is an operating day. It reports calendar days, weekend exclusions, listed holiday exclusions and the remaining business days. It does not estimate a route or look up a tracking number.
Worked example: a weekend and a US holiday
From Friday 4 September to Tuesday 8 September 2026 there are four calendar days. With the US calendar and Saturday disabled, Saturday and Sunday are weekends and Monday is the stored Labor Day holiday. Only Tuesday counts: one business day. Enable Saturday and the result becomes two business days. A holiday on an already excluded weekend is counted as a weekend once, not subtracted twice.
Match the service calendar before judging a promise
The model skips a listed holiday in either selected country. That conservative rule can differ from an actual carrier commitment: warehouse collection, linehaul movement and final delivery may follow different schedules. Select Saturday only if it counts toward the commitment you are measuring. The tool does not convert timezones or inspect delivery scans.
Turn measured time into a planning input
Record several comparable completed shipments before choosing a future transit range. Check that handling time and customs allowances are measured consistently, then enter that range in the delivery-date calculator. For stock planning, the reorder-point worksheet uses your own demand and lead-time assumptions; one completed shipment does not establish normal variability.
Calendar limits
Stored national holiday dates cover 2026-2027. Local holidays, company closures, strikes, weather, customs holds and factory shutdowns are not automatically represented. For an uncovered year, weekend arithmetic still works but holiday exclusions are incomplete. Confirm operational calendars with the warehouse and carrier.
Questions people ask about this
Answers written from the published rules, not from other people's summaries of them. Every figure quoted below is listed with its source at the foot of this page.
Every formula on this siteDoes the calculator include both endpoints?
It excludes the dispatch date and includes the delivery date if that date is an operating day. Equal dates produce zero elapsed calendar and business days.
Why are both countries selected?
The model conservatively excludes a stored holiday at either end of the route. Actual service calendars can differ, so this is an explicit assumption rather than proof that freight stops moving.
Does a weekend holiday get subtracted twice?
No. A date on an excluded weekend counts in the weekend total. It is not also subtracted in the holiday total.
Can I use this to prove a late-delivery refund is due?
No. Eligibility depends on the accepted service commitment, scans and carrier terms. This worksheet only measures the interval under your selected calendar.

| Published service transit windows and national holiday calendars Two datasets sit behind the delivery-date and transit-time tools, and neither is entered by the user. The first is each service's published transit window — FedEx Priority Overnight at one day, UPS Ground at one to five, Royal Mail Tracked 48, Worldwide Expedited at two to five plus a customs day, and roughly forty more. The second is 383 dated national public holidays across 18 countries for 2026 and 2027, applied at BOTH ends of the lane, with moon-dependent dates flagged approximate. Compiled rather than cited to a single document because no one document exists: transit windows come from each carrier's own service guide and several of those carriers refuse automated requests, and holidays come from each country's own calendar. Regional holidays and carrier-specific shutdowns are deliberately excluded — confirm with your carrier before promising a date around a holiday. | Carrier service guides and national public-holiday sources (compiled) | Not specifiedChecked 2026-08-25 | Corroborated |
