How to use Date Math Pro
Date Math Pro helps you calculate project timelines and business deadlines without worrying about weekends or holidays. This guide will show you how to get the most out of the tool.
📏 Measuring Time Between Dates
Use the Range Finder card when you have two specific dates and need to know exactly how far apart they are in business days.
Enter your Start Date and End Date.
Click Calculate to see the total Business Days (skipping weekends and your holiday list).
⏳ Finding Future Deadlines
Use the Date Shift card to find out what the date will be after a certain amount of time has passed.
"What is the date 15 Work Days from today?" This tool will jump over Saturdays and Sundays automatically to give you the real business deadline.
- ✓ Cal. Days: Simple calendar shifts (e.g., exactly 30 days from now).
- ✓ Work Days: Professional shifts that respect weekends and holidays.
