🧷 Practical Example: How the Date Due Calculator Works

Let’s see how the calculator works in a real scenario.

Example 1 – Project Deadline

Suppose your project started on October 1, 2025, and it’s due 45 days later.
You enter:

Start Date: October 1, 2025
Add: 45 days

👉 Result: November 15, 2025 (Saturday)

That’s your due date — now you can plan milestones, reminders, and deliverables accordingly.

Example 2 – Pregnancy Due Date

A pregnancy typically lasts 40 weeks (280 days).
If your last menstrual period (LMP) was on January 10, 2025, you enter:

Start Date: January 10, 2025
Add: 280 days

👉 Result: October 17, 2025 (Friday)

This gives you the estimated due date for your baby.
