One week ago — the same weekday as today, exactly one cycle back.
Type any number to find that date.
A week ago is the closest backward look that still feels current. Whatever you did last Tuesday, last Friday, last Sunday — that was 7 days ago. The result lands on the same weekday as today, which is why it's easy to remember and hard to misplace.
Seven days back is the upper edge of working memory for routine events. Most people can recall what they ate, who they met with, and what they were stressed about a week ago. Beyond that, days start to blur into each other unless something specific anchored them. The math is clean. Seven days equals 168 hours, half a moon cycle is roughly 14.7 days, so a week ago is just under a quarter of a lunation back.
Most agile teams hold a weekly retro looking back 7 days. The interval matches a full work cycle without being so long that details get lost.
If your free trial started a week ago, the renewal email is probably waiting in your inbox right now.
Doctors commonly ask 'when did this start?' If the answer is 7 days ago, you're at the threshold where most viral illnesses either resolve or get serious.
Many short-window refund policies expire at the 7-day mark — important if last week's purchase didn't work out.
Whatever happened in the news this past week, it played out across a week — the rhythm of headlines, the arc of a single news cycle, the time most weekly podcasts cover. A week ago is the same kind of day as today, with everything that's happened since stacked between.
Here's the corresponding date for each of the days around today:
