Syntax and Arguments

Gaining an understanding of the NETWORKDAYS.INTL formula in Excel is key. To do this, we have to look at each of its components. Options and arguments of start_date and end_date, weekend parameter, holidays and alternate weekend parameter must be examined. We’ll discuss each factor in detail, so you can get a complete grasp of the formula.

Start_date and end_date

The period between the start and end dates is a crucial aspect to consider while dealing with the NETWORKDAYS.INTL formula in Excel.

Start DateEnd Date

It’s essential to keep in mind that the dates should be entered using the YYYY/MM/DD format. Failure to do so might result in incorrect calculations.

When working with date ranges, one must ensure they don’t overlap. Overlapping can lead to erroneous results while applying math functions.

For instance, I once made an error in date entry while dedicatedly preparing a financial report ahead of a tight deadline. However, after being scrutinized by my boss, I realized my error and corrected it quickly before submitting the final version.

Making Excel work on weekends? NETWORKDAYS.INTL has got you covered, unless you’re working in North Korea.

Weekend parameter

The ‘Weekend parameter‘ in NETWORKDAYS.INTL Excel formula determines which days are considered as weekends. It allows you to customize your workweek according to your organization’s needs. By default, the WEEKEND argument is set to 1, with Saturday and Sunday considered as weekends.

Customization options include selecting different weekend patterns such as Sunday/Monday, Friday/Saturday or any other combination of weekdays representing the weekend. The WEEKEND argument also allows for selection of holidays that fall outside of weekends, making it easy to calculate the number of working days between two dates while factoring in holidays.

It’s important to note that modifying the weekend pattern may change the calculation results over a long period. Be aware of possible discrepancies when comparing results calculated with different weekend patterns at multiple time intervals.

Pro Tip: Use the NetworkDays_Intl function when you need a faster and easier method for calculating days between two dates excluding weekends or holidays.

I guess even Excel thinks we all need a break sometimes, hence the NETWORKDAYS.INTL function taking holidays into account.


For the purpose of calculation, it is important to consider days that are not considered as working days, including national and observed holidays.

  • Public holidays
  • Cultural holidays
  • National holidays
  • Religious holidays
  • Company-specific holidays

It is essential to ensure that all relevant non-working days are inputted while using the NETWORKDAYS.INTL formula.

It is crucial to have accurate and up-to-date information about public holiday dates. Failure to do so may result in miscalculations, leading to incorrect data analysis.

To avoid any discrepancies in calculating workdays accurately, it’s recommended to use reliable sources for holiday information or official government websites. This can also assist in identifying new or additional holidays announced in a specific country or region.

Proper verification and validation should be done when adding company-specific holiday data into the formula. It is also important to double-check the list before inputting this information to ensure data accuracy and consistency across all records.

Why limit your weekends to just Saturday and Sunday? NETWORKDAYS.INTL lets you choose your own adventures.

Alternative Weekend parameter

This Excel formula allows for selecting a different set of weekends using the ‘Weekend‘ parameter. By default, weekends are marked as Saturday and Sunday.

The ‘Alternative Weekend parameter‘ allows choosing any two days of the week to be marked as a weekend. This function is useful in industries where employees have different off-days, such as a five-day workweek that starts on Monday instead of Sunday.

Using this parameter, one can also add holidays to the list of non-working days and calculate the number of working days based on that.

A good practice is to keep a record of all non-working days in a separate sheet or table and refer to it while using the function.

Pro Tip: Use this formula when calculating project timelines or delivery dates considering non-working days for accurate results.

Need to calculate the number of workdays between two dates? NETWORKDAYS.INTL has got you covered, no matter how many international holidays and weekends get in the way.

Examples of using NETWORKDAYS.INTL

Need to calculate workdays between two dates? Or schedule a project start and end date? Look no further! The ‘Examples of using NETWORKDAYS.INTL’ section of ‘NETWORKDAYS.INTL: Excel Formulae Explained‘ is a great resource. It provides formulas to help you easily achieve a range of results. Sub-sections like counting workdays between two dates, excluding specific days or holidays, and calculating project duration with customized workweek and holidays give you the tools needed to streamline your work processes.

Counting workdays between two dates

When it comes to computing business days between two dates, several Excel formulae can be used. These functions are particularly useful, especially when calculating the working period needed for a project schedule. The following guide explains how you can compute workdays by leveraging NETWORKDAYS.INTL and NETWORKDAYS.INTL formulas.

  1. Step 1: Open the workbook with your project schedule and select a blank cell where you want to show the number of workdays.
  2. Step 2: Type in '=NETWORKDAYS.INTL' or '=NETWORKDAYS.INTL(start_date,end_date, [weekends], [holidays])' into the selected cell or formula bar.
  3. Step 3: Use 'Ctrl + A' or 'Shift+Tab' to view available parameters; start_date is your project’s commencement date and end_date is its planned finish date.
  4. Step 4: Next, proceed with weekends as an optional variable using numbers (from 1-7), where seven represents Sunday; for example, '=NETWORKDAYS.INTL(start_date,end_date,"0111111")'.
  5. Step 5: Include fiscal periods for holidays within double quotes or choose a specific holiday date range in another sheet defined as ‘Holidays,’ which would become '=NETWORKDAYS.INTL(start_date,end_date,"0111111", Holidays)'.

Note that this method offers flexibility since you can define all variables (start and end dates, holidays, weekends) explicitly. Additionally, it allows for retargeting weekends depending on your country of origin.

It is essential to keep track of working days while planning projects since tasks have varying timescales within which they must be completed. A planning oversight could result in delays in completing other tasks that depend on them.

In World War II Britain, crunching numbers was key when allocating resources effectively. Alan Turing, a pioneer in computer development, was at the forefront of developing computing systems that enabled cracking the Nazi Enigma code by speeding up complex calculations in a shorter time frame than previously obtainable.

Why take a vacation when you can just exclude holidays from your workdays using NETWORKDAYS.INTL?

Counting workdays excluding specific days or holidays

When calculating workdays, excluding holidays or specific days is important to prevent errors. To complete a calculation like this you must know the number of working days that have passed since the information was collected.

Here is a 5-step guide on how to count workdays while excluding specified dates:

  1. Enter the start date in a cell.
  2. Enter the end date in another cell.
  3. Select an empty cell and enter the formula =NETWORKDAYS.INTL(start_date,end_date,[weekend],[holidays]) with necessary parameters as per your requirement.
  4. The formula will calculate the number of non-weekend working days between the two dates. It can eliminate holidays as well, which can be added as an optional parameter.
  5. Press enter to get the result

Another advantage of using NETWORKDAYS.INTL is that it allows you to define custom weekend days. By default weekends are Saturday and Sunday, but if your business has different days off, you can customize it.

To ensure an accurate calculation every time, here are some suggestions:

  1. Above all other things maintain consistency in your data – this means keeping it updated and always referencing back to real-world calendars.
  2. Make sure to double-check holiday inputs before running any calculations – small mistakes here could lead to major issues down the line.
  3. Analyze trends over time – analyzing ‘Hot’ months with little activity could help you plan accordingly for future periods of low activity or downtime

Overall, counting workdays while excluding certain days requires precision and attention to detail. Proper use of Excel formulae like NETWORKDAYS.INTL ensures accuracy in complex calculations such as these so that businesses may make important decisions without any complications caused by incorrect data. Your project duration may be shorter than your holiday wish list, but at least with customized workweeks, you can clock out early.

Calculating project duration with customized workweek and holidays

When calculating the duration of a project with a customized workweek and holidays, it is essential to use specific formulae in Excel. With the help of the NETWORKDAYS.INTL and NETWORKDAYS.INTL functions, the days between two dates can be calculated while considering non-working days such as weekends and customized holidays.

In Table 1, an example is provided where we consider a project starting on January 1st, 2022 and ending on February 28th, 2022. Here, we have considered that Saturdays are working days but Sundays and January 26th (Republic Day) are non-working days. By applying the formula =NETWORKDAYS.INTL(A3,B3,"0000010",A7:A8), we can observe that there are 37 working days between these dates.

Start DateEnd DateCustom WeekendsHolidaysWorking Days
01-Jan-2228-Feb-22S26 Jan (Wed)=NETWORKDAYS.INTL(A3,B3,”0000010″,A7:A8)
01-Jan-2228-Feb-22S26 Jan (Wed)=NETWORDAYS.INTL(A9,B9,”0000010″,A7:A8)

It’s worth mentioning that weekdays/weekends vary according to regions and time zones; hence it’s crucial to customize date serialization accordingly.

To ensure accurate computations with NETWORKDAYS.INTL formulae, make sure that consistent date formats across dates in calculations, including custom weekends/holidays list.
