Mastering Smartsheet: NETWORKDAYS Formula

Efficient project planning requires accurate calculation of workdays, excluding weekends and holidays. SmartSheet, a robust work management tool, offers a variety of functions to streamline project scheduling and resource allocation. In this blog post, we will explore how to master the NETWORKDAYS formula in SmartSheet. By leveraging this powerful function, you can calculate the number of workdays between two dates, factor in holidays, and optimize your project timelines for enhanced productivity and efficiency.

Understanding the NETWORKDAYS Formula:

The NETWORKDAYS formula in SmartSheet allows you to calculate the number of workdays (excluding weekends and specified holidays) between two given dates. Its syntax is as follows: =NETWORKDAYS(start_date, end_date, [holidays]). Here's what each parameter represents:

"start_date" refers to the beginning date of the period for which you want to calculate workdays.

"end_date" denotes the end date of the period.

"holidays" (optional) represents a range or list of dates to exclude from the calculation, such as public holidays or company-specific non-working days.

Calculating Workdays between Dates:

To use the NETWORKDAYS formula to calculate workdays between two dates, follow these steps:

Identify the start and end dates: Determine the dates that define the desired period for calculating workdays.

Apply the NETWORKDAYS formula: In an empty cell, enter the formula =NETWORKDAYS(start_date, end_date, [holidays]), replacing the parameters with the appropriate cell references or values.

Handling Holidays:

SmartSheet's NETWORKDAYS formula allows you to exclude specific holidays from the workday calculation. Here's how to handle holidays effectively:

Create a holiday list: Prepare a separate column or range where you can enter the holidays to exclude from the workday calculation.

Specify the holiday range in the formula: Include the holiday list as the third parameter in the NETWORKDAYS formula, ensuring it covers the entire range of holiday dates.

Adjusting for Non-standard Working Days:

If your project follows a non-standard workweek with different working days or shifts, you can customize the NETWORKDAYS formula to account for these variations. Use additional formulas or functions, such as IF or WEEKDAY, to conditionally exclude specific days based on your project's unique schedule.

Utilizing Workday Differences for Project Planning:

The result of the NETWORKDAYS formula can be further utilized in project planning and scheduling. By subtracting the calculated workdays from the total calendar days, you can determine the number of non-working days, weekends, or holidays within a specific period.

Automating Workday Calculations:

To automate workday calculations in SmartSheet, consider using the NETWORKDAYS formula in conjunction with SmartSheet's automation features. Set up rules that update workday calculations automatically based on changes in project schedules, start dates, or other relevant factors.


Mastering the NETWORKDAYS formula in SmartSheet allows you to accurately calculate workdays between two dates, considering weekends and specified holidays. By leveraging this powerful function, you can optimize project planning, resource allocation, and scheduling, resulting in improved productivity and efficiency. Whether you need to determine project durations, allocate resources, or track progress, the NETWORKDAYS formula is a valuable tool for effective project management in SmartSheet.
