Number of Weekdays Between Two Dates Calculator

What is a Number of Weekdays Between Two Dates Calculator?

A Number of Weekdays Between Two Dates Calculator is a tool that determines the count of weekdays (typically Monday through Friday) between two specified dates. This calculator is particularly useful for business planning, project management, and calculating work days for payroll or leave purposes.

Formula

The formula to calculate the number of weekdays between two dates is:

\[ \text{Weekdays} = \text{Total Days} - \text{Weekend Days} \]

Where:

• \(\text{Weekdays}\) is the number of weekdays between the two dates
• \(\text{Total Days}\) is the total number of days between the start and end dates, inclusive
• \(\text{Weekend Days}\) is the number of Saturdays and Sundays within the date range

Calculation Steps

1. Calculate the total number of days between the start and end dates, inclusive:

   \[ \text{Total Days} = \text{End Date} - \text{Start Date} + 1 \]

2. Count the number of weekend days (Saturdays and Sundays) within the date range
3. Subtract the weekend days from the total days to get the number of weekdays:

   \[ \text{Weekdays} = \text{Total Days} - \text{Weekend Days} \]

Example

Let's calculate the number of weekdays between March 1, 2023, and March 15, 2023:

1. Calculate total days:

   \[ \begin{align} \text{Total Days} &= \text{March 15, 2023} - \text{March 1, 2023} + 1 \\[10pt] &= 15 \text{ days} \end{align} \]

2. Count weekend days:

   There are 2 full weekends (4 days) plus 1 additional Saturday in this range.

   \[ \text{Weekend Days} = 5 \]

3. Calculate weekdays:

   \[ \begin{align} \text{Weekdays} &= \text{Total Days} - \text{Weekend Days} \\[10pt] &= 15 - 5 \\[10pt] &= 10 \text{ weekdays} \end{align} \]
