Direct answer
Use the approval date if the rule says the deadline begins on approval, or the next business day after approval if the rule says counting starts after approval.
Use this page for searches like "deadline starts after approval what date to use" when the answer depends on a real workplace detail, not just a formula.
Open Business Days From Today CalculatorRealistic scenario
Approval-based deadlines are messy because the invoice, request, and approval can all happen on different dates. The right start date comes from the wording, not from the date that feels most convenient.
Request submitted June 3, approved June 6. Rule says 10 business days after approval. Start counting from June 7 if the rule excludes the approval day.
Calculation frame
Deadline = approved start date + stated business-day or calendar-day window.

How to check it
Key checks
- Identify the event that starts the clock.
- Read whether the approval day counts.
- Use business days only if the rule says business days.
- Skip weekends and excluded holidays when needed.
- Save the approval date with the final deadline.
Details people usually miss
If approval happens after hours, the next business day may be safer for internal workflows.
If the terms say “within 10 days of approval,” the approval day may be treated differently than “10 days after approval.”
If invoice date and approval date differ, do not use invoice date unless the rule says so.
Common mistakes
Do not count from the request date if approval starts the clock.
Do not switch between calendar days and business days.
Do not count the start day without checking the wording.
