Add or Subtract Days

Need help adding or subtracting days to or from a date? Use the online ‘Add Days’ tool and add years, months, weeks, and days to any date. Choose a start date, then the years, months, and days to add to your start date in the respective fields. Once done, click ‘Calculate Duration.’ The result is the new date ahead of the start date by the period you chose.

Otherwise, if you want to calculate a date in the past that is behind your current date by a certain number of years, months, weeks, and days, use the ‘Subtract Days’ tool. Enter the start date and the number of years, months, weeks, or days you want to go back by. Now click ‘Calculate Duration,’ and you get the required date in the past.

In addition, you can view the result in various formats, such as years, months, weeks, days, hours, minutes, and seconds. For example, to determine how many days there are in two years and seven months, enter the start date and select the desired duration of the year and month. You will get the new date and discover that the number of days within this span is 943.

Why should you use an online date calculator? Because it is the easiest and most accurate way to add or subtract any number of years, months, weeks, or days to your desired date. The calculator saves you time and effort while ensuring accuracy in your date calculations, whether date plus days or date minus days. Also, a manual calculation may add errors or inaccuracies to the result.

The date calculator is handy in many situations, such as scheduling appointments, setting contract dates, or planning events. With this tool, users can easily determine the new date for a future event or calculate the number of days that have passed since a particular date by adding or subtracting the required number of days.

Also, in cases where you must determine only the business days, you are free to use the additional features provided by our ‘Working Days Calculator’, which gives you the option to exclude weekends or holidays from the calculation.
