Date Calculator: Add, Subtract, and Measure Time

Count the days between dates or find a future deadline.

Whether you are counting down the days until a family vacation, determining a project deadline, or calculating the exact number of days between two historical events, our Date Calculator makes it simple. No more manual calendar counting or confusion over leap years—get precise results for any date in the past, present, or future.

Powerful Date Features

On familyhealthcalc.com, we’ve built this tool to handle the complex nuances of the Gregorian calendar:

1. The “Between Dates” Tool

Calculate the exact span between two points in time.

• The Result: See the duration broken down into years, months, weeks, and total days.
• Inclusive Option: Choose whether to include the end date in the count (useful for travel planning).

2. The “Deadline” Tool

Find a specific date by adding or subtracting time.

• Example: “What is 90 days from today?”
• Business Use: Calculate “Net 30” or “Net 60” payment terms with a single click.

3. Business Days vs. Calendar Days

Perfect for the UK, US, and Canada, our calculator can optionally skip weekends (Saturdays and Sundays) to give you the total number of working days for a project.

Practical Uses for Your Family
