How to Calculate Date Ranges

Calculating the number of days between two dates is a common task in various fields, including project management, event planning, and financial analysis. This process involves determining the duration between a start date and an end date.

Formula and Components

The general formula for calculating the number of days between two dates is:

\[Days Between = End Date - Start Date + 1\]

Where:

• \(Start Date\) is the initial date of the range
• \(End Date\) is the final date of the range
• We add 1 to include both the start and end dates in the count

Calculation Steps

1. Identify the start date
2. Identify the end date
3. Calculate the difference between the two dates
4. Add 1 to include both the start and end dates

Example Calculation

Let's calculate the number of days between June 15, 2025, and July 10, 2025:

1. Start Date: June 15, 2025
2. End Date: July 10, 2025
3. Calculate the difference:
   July 10, 2025 - June 15, 2025 + 1 = 25 days

Therefore, there are 25 days between June 15, 2025, and July 10, 2025.
