How this calculator works
Sixty days is a common notice, return and cooling-off period, and it is close to two months without ever matching it exactly. The calculator adds or subtracts sixty whole calendar days, so the result is independent of month lengths and leap years. Counting weekdays inside the span gives a working-days estimate; it does not remove statutory holidays, which you would subtract separately.
Formula
result = fromOrdinal(O(start date) + 60) forward, or fromOrdinal(O(start date) - 60) backward. The span is 8 weeks and 4 days. Weekdays inside counts Monday to Friday dates in the half-open interval between the two dates.
Worked example
60 days after 2026-11-01 is 2026-12-31, a Thursday, so the span is 8 weeks and 4 days with 44 weekdays inside. 60 days before 2026-11-01 is 2026-09-02, a Wednesday.

Frequently asked questions
Is 60 days two months?
Not exactly. Two months are 59 days for a short pair such as April and May and 62 days for July and August. Sixty days is the safer figure when a policy states days rather than months.
How do I count a 60-day return window?
Start from the day after delivery, as most policies do, and stop on the sixtieth day. Some retailers stop on the day the return is postmarked and others on the day it arrives, so read the policy wording before relying on the final date.
Does the count include weekends?
Yes. A day is a calendar day here. The weekdays-inside figure is provided for planning but is not the count itself.
