How to Use the Calculator

This Lead Time Calculator helps you determine the number of days between the order date and the delivery date. Simply follow these instructions:

  1. Enter the Order Date – the date when the order was placed.
  2. Enter the Delivery Date – the date when the items are expected to be delivered.
  3. Click the Calculate button to see the result.

How it Calculates the Results

The calculator computes the lead time by subtracting the order date from the delivery date. It then converts the time difference from milliseconds into days, taking into consideration the differences caused by full days only.

Limitations

Please note that the calculator assumes every day, including weekends and holidays, counts towards the lead time. It does not account for public holidays or non-working days specific to your region or industry. If you need to exclude certain days, adjust the delivery date accordingly.
