How to Add Days to a Date

Using a Date Calculator to Add Time

A date calculator is the most reliable way to find a future date. Here's how it works:

1. Enter a Start Date: Use the calendar picker to choose your initial date.
2. Enter the Duration to Add: Input the number of years, months, weeks, and/or days you want to add. You can combine them.
3. Calculate the New Date: The tool will instantly compute the resulting date. For example, adding 90 days to May 1st will give you July 30th.

Why It's Better Than Manual Calculation

A date calculator automatically manages the different lengths of months (e.g., 30 or 31 days) and correctly accounts for the extra day in a leap year. This prevents common errors and provides an accurate result in seconds.
