Work backwards from a date by subtracting any number of days, weeks, months or years, and see exactly which earlier calendar date you land on. It answers questions like what date was 90 days ago, when a 30 day notice period must start to hit a target, or the date that was six months before an event. The result includes the day of the week, which helps when you need the previous business day or want to avoid a weekend. Calendar rules are handled for you, so crossing month boundaries and leap years never throws the count off. Enter your reference date and the amounts to remove, and the earlier date appears instantly. All of the calculation happens locally in your browser with nothing sent anywhere.
