Here is a handy trick to calculate last day of any month.
Assuming y and m contain the year & month for which you want to find the last day’s date, write
=DATE(y, m+1,0)
That is right, you can use ZERO (0) as the day.
When you do this, Excel tells us the last day of previous month.
How to calculate last day if I have a date in that month:
Instead of year and month, if you know a date & you want to find what is the last date… then use:
=EOMONTH(date, 0)
How to calculate the last working day of a month?
If you just care about working days.. then use:
=WORKDAY(DATE(y,m+1,1), -1)
This will give us the last working day of a month.
Dealing with holidays:
Very simple. Pass on a list of holidays to WORKDAY as last parameter. Like this:
=WORKDAY(DATE(y,m+1,1), -1, F1:F20)
This assumes, F1:F20 has a list of holiday dates.
Dealing with different weekend types:
Not everyone observes Saturday & Sunday as weekend. For example, I do not work on Tuesdays. You might have Sunday thru Thursday work week. If so,
use WORKDAY.INTL function, like this:
=WORKDAY.INTL(DATE(y,m+1,1), -1, 7)
Weekend type 7 is for Friday & Saturday weekend.

CONGRATS on the book!
Thanks for this podcast. It's great to hear about your disaster and recovery. It's a reminder that we're all human. None of this skill came easily.
Thank you Oz. I believe that we learn most by analyzing our mistakes.
Hey chandoo
this really a good lesson learned
but as I have already stated in one of my previous email that it would be more helpful for us if you could release videos of your classes for us
thanks
The article gave me motivation, especially you describing the terrible disaster that you faced but how to get back from the setbacks. Thanks for that, but with video this will be more fun.
Hi Nafi,
Thanks for your comments. Please note that this is (and will be) audio podcast. For videos, I suggest subscribing to our YouTube channel. No point listening to audio and saying its not video.
You always motivate me with respect of the tools in excel. How we can really exploit it to the fullest. Thanks very much
Thank you Amankwah... 🙂
Thank you very much, Chandoo, for your excellent lessons, I am anxious to learn so valuable tips and tricks from you, keep up the great job!
I truly appreciate the transcripts of the podcasts, because as a speaker of English as a second language, it allows me to fully understand the material. It'd be great if you can add transcripts to your online courses too, I am sure people will welcome this feature.
Dashboards for Excel has arrived in Laguna Beach, CA! Thanks!
Now I need to make time to "learn and inwardly digest" its contents as one of my high school teachers would admonish us!
