Microsoft Excel Tutorial: Calculate Work Days Until End of the Month using EOMONTH & WORKDAY Functions.

Welcome back to the MrExcel netcast where we answer your Excel questions and provide helpful tips and tricks. I'm Bill Jelen and today we have a question from Vishnu in India. If you have a question for the netcast, don't hesitate to leave a voicemail or send us an email and we'll feature it in a future podcast.

Coincidentally, Vishnu's question ties in perfectly with our previous episode where we discussed how to find the end of the month. He wants to know how to find the number of work days before the end of the month, not just the last day. He mentioned using the EOMONTH function, which is part of the Analysis Toolpak. If you're using Excel 2003 or earlier, make sure to enable the Analysis Toolpak under Tools > Add-Ins. For those using Excel 2007 or later, the function is automatically available.

To find the number of work days before the end of the month, we'll use a combination of the EOMONTH and WORKDAY functions. First, we'll use the EOMONTH function to find the end of the month for a given date. Then, we'll use the WORKDAY function to calculate the number of work days before that date. One thing to note is that these functions do not automatically format the cell as a date, so we'll need to do that manually by selecting the cells and using the Format Cells option.

The WORKDAY function is a powerful tool that allows us to calculate dates based on work days, rather than just calendar days. In this case, we'll use a negative number to find the work days before the end of the month. For example, if we want to know the date that is one work day before the end of the month, we'll use -1 as the second argument in the function. We can also use this method to find multiple work days before the end of the month by simply changing the number in the second argument.

Thanks to Vishnu for sending in this question and allowing us to showcase this useful Excel function. If you have a question for the podcast, don't hesitate to send it in. Thanks for tuning in and we'll see you next time for another netcast from MrExcel.

How can you figure out a date that is a certain number or workdays BEFORE a date? On the last episode of The Lab with Leo Laporte, I showed how to calculate a date 45 workdays after a certain date. Todays question is how to calculate the date 5 days before the end of the month. Episode 560 shows you how to calculate this value.
