What if we have a deadline of 30 days for the completion of a process? You could simply add 30 to the date started, or the date received. Even though the entry is formatted as a date, these types of date calculations work because every date in Excel has a numeric value behind it, starting with 1 at the beginning of the year 1900, and it grows incrementally every day. Another common calculation is to calculate the difference between two dates, such as the date received or the date started and the actual completion date. While these basic calculations may be helpful for some projects, they don’t exclude weekends. And, what if you’d also like to ignore holidays? For these answers, we need the WORKDAY and NETWORKDAYS functions. Both of these functions assume the work week runs from Monday to Friday. If you need different options for working or business days, there are international variations to these functions. To see examples of how to calculate dates and exclude weekends and holidays, download a sample file of these Excel functions. The Excel WORKDAY FunctionThere are 3 parts to the WORKDAY function: the start day, the number of days you want to add, and the holidays you want to exclude. This last argument is optional. =WORKDAY(start_date, days, [holidays]) If you’d like to exclude holidays in addition to weekends, create a range of holidays to refer to in the formula. This list may include multiple years and can be stored in a different worksheet or even another workbook.The WORKDAY function would also be helpful for other applications, such as creating a reporting timetable or building a simple project timeline. It’s good to know the WORKDAY function does not count the start day. The Excel NETWORKDAYS FunctionIf you’d like to calculate the difference between two dates while excluding weekends and holidays, use the NETWORKDAYS function instead. This also looks for 3 arguments: the start date, the end date, and optional holidays. =NETWORKDAYS(start_date, end_date, [holidays]) Unlike the WORKDAY function, the NETWORKDAYS function does include or count the start day.Try these functions for more accurate results when you are calculating dates in Excel.
