How can I figure out how many days are between two dates?
Put the start and finish dates into the calculator above. It automatically takes the earlier date away from the later date and shows the result in a number of ways, including years, months, days, total weeks, total days, hours, minutes, and seconds. The calculator takes care of leap years and months with different numbers of days on its own.
How do you figure out the difference between two dates?
End Date - Start Date is the basic formula. To figure out the years, months, and days between two dates, first figure out the full years between them, then the full months in the time that is left, and finally the days that are left. The DATEDIF function in Excel does this: =DATEDIF(A1, B1, "Y") for years, "M" for months, and "D" for days.
How do I find out how many business days are between two dates?
Weekends (Saturday and Sunday) are not business days. Count all the days on the calendar between your dates, and then take away the weekends. For instance, a week from Monday to Friday has 5 business days, even though 7 calendar days have passed. You can automatically figure out the number of days between two dates in Excel by using =NETWORKDAYS(start_date, end_date).
Should I count the end date or not when figuring out dates?
It depends on the situation. Include the end date for rental periods, hospital stays, and counting that includes all nights (for example, 3 nights = check-in day through checkout day). When figuring out someone's age, how much time has passed, or most deadlines, don't include the finish date. If you're not sure, ask which strategy is best for your situation.
How do I figure out how many months there between two dates?
Count the full months between the start date and the finish date. It is exactly three months from June 15 to September 15. For months that aren't full, count the entire months first and then write down the extra days. Our calculator automatically shows both full months and the number of days left.
What does the calculator do with leap years?
The calculator automatically finds leap years and changes February to 29 days. Any calculation that goes through February checks to see if that year is divisible by 4 (or 400 if it is a century year). This makes sure that the day counts are correct for durations of more than one year.
What is the difference between working days and calendar days?
Every day on the calendar is a calendar day. Most of the time, working days are merely Monday through Friday, and public holidays are usually not included. There are about 21 to 22 working days in a 30-day calendar. Deadlines set by law or contract should state which method of counting applies.
How do I figure out my precise age in years, months, and days?
Put your birth date as the start date and the date of today as the end date. The calculator shows you just how old you are. For instance, if you were born on March 15, 1990, and today is December 21, 2025, you would be exactly 35 years, 9 months, and 6 days old.
What will happen if I put the end date before the start date?
The calculator finds dates that are in the wrong order and marks them for you. Then it figures out and shows the absolute difference, which is the same amount of time no matter what order the dates are in. This is helpful when figuring out how long ago something happened or when checking that the dates are right.
How can I figure out how long an employee has been with the company since they were hired?
Use the hire date as your start date and today's date (or the finish date) as your end date. The calculator indicates how long someone has worked there in years, months, and days. This is great for HR tasks like figuring out when someone is eligible for benefits, when their pension will vest, and when they will get a service award.
