Quick answer
Three business days usually means three weekdays after the starting day, skipping Saturday and Sunday.
For example, if something starts on a Monday and you are told it will take 3 business days, the three business days are normally Tuesday, Wednesday, and Thursday. So the result is usually Thursday.
| Starting day | 3 business days later |
|---|---|
| Monday | Thursday |
| Tuesday | Friday |
| Wednesday | Monday |
| Thursday | Tuesday |
| Friday | Wednesday |
These examples assume there are no public holidays in the period and that the starting day itself is not counted as Day 1.
Do weekends count as business days?
Usually, no. Saturday and Sunday are normally excluded from a business-day calculation. That is why 3 business days can span more than 3 calendar days.
For example:
- Start on Wednesday → Thursday is Day 1, Friday is Day 2, Monday is Day 3.
- Start on Friday → Monday is Day 1, Tuesday is Day 2, Wednesday is Day 3.
Do holidays count?
Often they do not, but the exact rule depends on the organization, country, contract, bank, shipping company, or government agency involved. A public holiday that falls on a weekday may push the deadline back by another day.
Because holiday rules vary, confirm important legal, banking, shipping, or government deadlines with the organization that set the deadline.
Is 3 business days the same as 72 hours?
No. Three business days is not necessarily 72 hours. Business days are based on working days, while 72 hours is a continuous time period that includes nights and weekends.
For example, 72 hours after Friday afternoon is Monday afternoon. But 3 business days after Friday is usually Wednesday, assuming no holidays.
Does the starting day count?
Often the starting day does not count when someone says “within 3 business days” or “3 business days from today.” Counting usually begins with the next business day. However, wording and industry rules can differ.
If a deadline matters, check whether the sender means:
- 3 business days after today, or
- including today as Day 1.
