What does the policy do if a due date falls on a weekend?

It moves the due date to the next business day after excluding weekends and holidays you set.

Do holidays also move the due date?

Yes when they are excluded. The next business day can move past both weekends and holidays.

Should I document inclusive vs exclusive mode?

Yes. Inclusive can keep the same day if valid; exclusive always moves forward.

How do weekend patterns affect the rule?

Custom patterns like Fri–Sat or Sun–Thu change which days are excluded, shifting the next business day.

No. It’s educational. Results depend on your inputs and assumptions and are not guaranteed.

Policy wording

If a due date falls on a weekend, move to the next business day

The “due date falls on weekend next business day” policy shifts deadlines off non-working days. If a date lands on a weekend or holiday you exclude, the due date moves forward to the next business day. Use the business day calculator to set weekend pattern, holiday preset, and mode, then document the rule so everyone knows how dates will roll.

Quick answer: move the date forward

If a due date lands on an excluded weekend or holiday, push it to the next business day.
Custom weekend patterns change which days are excluded.
Inclusive vs exclusive mode defines whether the current day can still count.

Document the rule clearly

Write down the weekend pattern, the holiday preset, any custom holidays, and whether you use inclusive or exclusive mode. If the due date hits a blocked day, you’ll have the proof that it should roll forward. This keeps billing, compliance, and customer teams aligned on the same interpretation.
