How this is worked out
Counting 20 weeks back from 9 October 2026 gives Friday, May 22, 2026. Every day in between is counted, weekends and public holidays included, which is how deadlines, notice periods and delivery windows are normally expressed.
If your count should skip weekends, use the business-day figure instead: 100 working days separate the two dates. Public holidays are not deducted, because they differ by country — check your own calendar if a holiday falls inside the span.
