Let's say you're planning a project that starts on September 1, 2023, and is expected to last 2 years, 6 months, and 15 days

  2. Enter 'September 1, 2023' in the Start Date field.
  3. Input '2' in the Years field, '6' in the Months field, and '15' in the Days field.
  4. Click the Calculate button.
  5. The displayed result will be the expected end date of your project.

→ Subtraction

Suppose you want to find out the date 90 days before an upcoming event on December 31, 2023, to start the event preparations.

  1. Open the Date Time Calculator and select "Subtract" from the Operation Type.
  2. Enter 'December 31, 2023' in the Start Date field.

  2. Enter 'December 31, 2023' in the Start Date field.
