Introduction
This month calculator finds the number of months and days between any two dates. Just pick a start date and an end date, and the tool does the rest. It shows your result in months, days, weeks, hours, and minutes. It also counts business days and weekend days for you.
The order of the dates does not matter. If you put the later date first, the calculator will still give the right answer. You can also click the "Today" button to use today's date without typing it in.
Along with the results, you get a step-by-step breakdown that shows how each number was found. Charts help you see how the days split across each calendar month and how many fall on weekdays versus weekends. This tool tells you how far apart two dates are, so you can plan a project or track a deadline.

How to Count Months Between Two Dates
A month calculator helps you find the exact time between any two dates. You pick a start date and an end date, and it tells you how many months and days sit between them. This is useful when you need to track a deadline, figure out how long a project lasted, or count down to an event.
Why Counting Months Is Tricky
Not all months have the same number of days. February has 28 days, or 29 in a leap year.1 Months like January and March have 31. This means you cannot just divide a number of days by 30 and get a perfect answer. A good month calculator walks through each calendar month one at a time so the count stays accurate.
Months vs. Days vs. Weeks
People measure time in different units depending on the situation. A doctor might track a pregnancy in weeks. A landlord counts rent by the month. A lawyer may need the exact number of business days. Each unit gives you a slightly different view of the same span of time, so it helps to see all of them at once.
What Are Business Days?
Business days are weekdays: Monday through Friday. They leave out Saturday and Sunday. Many work deadlines and shipping estimates use business days instead of total days. Knowing the split between weekdays and weekend days can help you plan more clearly.
When You Might Need This
People commonly count months between dates for lease agreements, loan terms, age calculations, school semesters, and travel planning. Any time you need to know how much time has passed or how much time is left, a month calculator gives you a fast and reliable answer.
