The First Response Due Date Calculator determines the deadline for when a response is required based on a specified starting date and a given response time. This calculator is especially useful in business operations, legal compliance, service-level agreements (SLAs), insurance processing, and customer service workflows.
It belongs to the Deadline and Time Management calculator category. It helps reduce errors in manual date tracking and ensures accurate scheduling of due dates.
Formula of First Response Due Date Calculator
First Response Due Date = Start Date + Allowed Response Time
Where:
- Start Date is the date the event, request, or trigger occurred
- Allowed Response Time is the number of days, hours, or business days within which a reply must be made
Notes:
- If response time is in calendar days: Due Date = Start Date + N days
- If response time is in business days: Exclude weekends and holidays from the count
Example: A 5-business-day deadline starting on Monday will land on the following Monday, excluding Saturday and Sunday
To calculate business days, you need a function that automatically skips non-working days, which may vary by country or organization.

Example of First Response Due Date Calculator
Let’s say you receive a formal customer complaint on March 4, and your company policy requires a response within 5 business days.
Step 1: Start Date = March 4
Step 2: Response Time = 5 business days
Skip the weekend: March 9 and 10
Count days:
- March 4 = Day 1
- March 5 = Day 2
- March 6 = Day 3
- March 7 = Day 4
- March 8 = Day 5
The due date is March 8, assuming no holidays are in between.
