To add days, enter the number of days (or other time units) into the "time difference" field. For example, if you're just starting an intense three-month tap dancing course and want to know what day will be 90 days from today, input today's date. The time difference will be the time between dates e.g., how many days the school year lasted.Ĭhoose a start date from which you're going to add or subtract days. Input the date marking the end of a period e.g., the last day of school. Input the date that begins a given period as the start date e.g., the first day of a school year.

The time difference will be the time left until the date. Select the date you are waiting for in the "end date" field.
