Weeks ago is for spans people already think of in sevens: a fortnight, a biweekly pay period, or “two weeks ago.” The page shows the date and the day count 7N beside it, so it is not a renamed days tool with the 7 hidden.
To move a pay period forward, use the Weeks From Now Calculator. Day-by-day look-backs belong on Days Ago.
A week is seven calendar days
Each week is exactly seven midnights, not “about a week” and not five workdays. Two weeks ago is 14 days before today. The note under the date prints that day count.
Pay periods still include the weekend
A biweekly pay period on this page is 14 calendar days. It does not drop Saturday and Sunday. If the period should be ten business days, count those on the business-days page.
Worked example: 2 weeks before 13 November 2026
If today is 13 November 2026, 2 weeks ago is Friday, 2026-10-30. The note shows 14 days, which is 2 × 7.
\[ 2026\text{-}11\text{-}13-14\,\mathrm{d} \]
Frequently asked questions
Is a week seven days or five workdays?
Seven calendar days. Weekends stay inside the span.
What does the day count under the date mean?
It is 7 times the number of weeks, so two weeks is labeled 14 days.
Can I enter half a week?
The count is truncated to a whole number of weeks. Use Days Ago for a 3-day or 10-day step.
Why can’t the number be negative?
A future week is the Weeks From Now job. This page only looks backward.
Does the week start on Monday?
No week-start rule is applied. The page subtracts 7N days from today’s date.

Assumptions and limitations
