A free, advanced tool with detailed results and a business day calculator.

Whether you're planning a project, setting a deadline, or simply curious, questions like "What is the date 90 days from today?" are incredibly common. While it seems like a simple task, manual date calculations are often prone to errors due to varying month lengths and leap years.

How to Use the Date Calculator: A Section-by-Section Guide

This calculator is engineered for an interactive experience. The results update automatically as you change any input, providing instant answers without needing a "calculate" button.

Section 1: Start & Result

This is the core of the calculator where you set your starting point and see the final answer.

  • Skip Weekends (Advanced Option): Check this box to transform the tool into a powerful business days calculator. It will only count Mondays through Fridays, which is essential for professional timelines.

Understanding the Calculation Logic and Features

Our date difference calculator uses a robust algorithm to handle calendar complexities with precision.

The Order of Operations

To ensure consistent results, the calculator performs operations in a specific sequence:

  1. Years: It first adds or subtracts the full years. This correctly handles leap years.
  2. Months: Next, it adds or subtracts the months, intelligently adjusting for month-end dates (e.g., adding 1 month to Jan 31 results in the last day of Feb).
  3. Days (including Weeks): Finally, it adds or subtracts the total number of days.

The Business Days Calculation

When you use the "Skip weekends" feature, the logic changes. Instead of simply adding a block of time, the business days calculator iterates one day at a time, checking if each day is a weekday.

This feature is crucial for answering questions like, "What is the date 60 business days from today?"


Practical Applications: Who Needs a Date Calculator?

A tool to calculate dates is invaluable in many professional and personal scenarios:

Project Management

Determine the exact deadline for a project that takes 45 working days to complete. Use our business days calculator for accurate timelines.

Legal and Contracts

Accurately calculate contract periods, notice periods (e.g., "30 days notice"), and legal deadlines with confidence.

Event Planning

Use it as a countdown calculator. "How many days until my vacation?" Or plan ahead: "The wedding is in 6 months, what will be the exact date?"

Health and Medicine

Track pregnancy milestones (e.g., "what is 40 weeks from today?"), schedule follow-up appointments, or determine medication schedules.


Frequently Asked Questions (FAQ)

When this option is checked, the calculator only counts weekdays (Monday, Tuesday, Wednesday, Thursday, Friday). It will skip over any Saturdays and Sundays when adding or subtracting days. This is perfect for calculating business-related deadlines.

No. The "Skip weekends" feature only excludes Saturdays and Sundays. Public holidays vary greatly by country and region, so they are not automatically excluded. For precise business timelines involving holidays, you would need to manually account for any holidays that fall within your date range.

This tool is specifically designed to add or subtract a duration from a start date to find a new date. If you need to find the total time *between* two known dates, we recommend using our dedicated Date to Date Calculator, which is built for that exact purpose.
