An effective date or as of date is the date upon which something is considered to take effect. This may be different from the date upon which the event actually occurs or is recorded.
Famous quotes containing the words effective and/or date:
“I know no method to secure the repeal of bad or obnoxious laws so effective as their stringent execution.”
—Ulysses S. Grant (1822–1885)
“A preschool child does not emerge from your toddler on a given date or birthday. He becomes a child when he ceases to be a wayward, confusing, unpredictable and often balky person-in-the- making, and becomes a comparatively cooperative, eager-and-easy-to-please real human being—at least 60 per cent of the time.”
—Penelope Leach (20th century)
