Which tool to use
Pick by the question you are asking. A deadline such as 30 or 90 days from a date comes from the date calculator. The gap between two dates in days, weeks and months is days between dates; if only working days count, as for a notice period or a delivery promise, use the business days calculator. Someone's exact age, or how old they will be on a given day, is the age calculator. A countdown to a birthday or a holiday is days until, and the week number for a planner or a sprint is week number.
