The date calculators answer two different questions. The age calculator counts from a birth date to today, while the date difference calculator measures between any two dates and separates working days from calendar days, which is what notice periods and project deadlines usually turn on.

The GPA calculator weights each grade by its credit hours rather than treating all courses equally, which is how institutions actually compute it. Check your own school's grade points before relying on it, since the mapping from letter to number is not universal.
