Legal Deadline Calculator – Accurate and Easy

Our legal deadline calculator tool helps you determine the exact due date for your legal tasks.

How to Use the Legal Deadline Calculator

1. Enter the start date in the “Start Date” field. Use the date picker to select the correct date.

2. Enter the number of days to add in the “Days to Add” field. Ensure the number is positive and valid.

3. If you want to count only business days (excluding weekends), check the “Business Days Only” checkbox.

4. Click the “Calculate” button to see the result in the “Result” field.

How the Calculator Works

The Legal Deadline Calculator takes a start date and a number of days to add. It will output the resulting date after adding those days. If “Business Days Only” is checked, the calculator will skip weekends when counting.

The calculator uses standard JavaScript Date operations to increment the date and checks the day of the week to skip weekends if required.


The calculator does not account for holidays or any specific non-working days other than weekends. It strictly considers only regular calendar and business days.
