How to convert weeks to days

days = weeks × 7

The seven-day week (604,800 seconds) is a purely cultural unit — it tracks no astronomical cycle, yet nearly every civilization adopted it.

The civil day is exactly 86,400 seconds. Earth's actual rotation drifts slightly, which is why leap seconds occasionally exist.
