Rounding time to nearest minute or quarter hour etc. [formulas]

Rounding time to nearest minute or quarter hour etc. [formulas]

The other day, I was building a spreadsheet to calculate FTE (full time equivalent) for staff based on hours worked on various days in a fortnight. While building the spreadsheet, I came across an interesting problem. Rounding Time to nearest minute.  We can’t use ROUND() or MROUND() to round time as these formulas aren’t designed to work with time values. Although time values are technically decimal, rounding time to nearest minute (or quarter hour etc.) can be tricky when usual round formulas. Let me share a few formulas to round time to nearest point.

Let’s say you have a time value (either user input or calculated) in cell A1.

Use below formulas to round time in A1.

SUMPRODUCT Vs. Power Query on Mt. KauKau

When faced with tough problems I react in one of three ways

  1. Come up with ingenious solutions
  2. See if a simpler cheat solution is possible

When faced with a tricky time sheet summary problem (as outlined above), after initial lethargy I wanted to solve it.

Jo’s first keyboard shortcut

Jo, my lovely wife quit her job as my partner in crime at Chandoo.org recently and took up a lucrative position at NZ govt. agency. The other day I asked her “how was your day?” when she got home. She smiled and said, “I learned my first Excel shortcut!”.
Guess what it is?

F4.

That is right. The mighty F4 key. You can use it to repeat any action.

Start your bar charts from zero – Excel geeks screaming at you from mountain top

Here is a simple but vital charting rule.

Start your bar (or column) charts from zero.

To illustrate why you should do this, let me share a personal example.

Over the weekend, the Jon Peltier visited Wellington. He is staying with Jeff (who occasionally guest blogs on Chandoo.org). On Sunday, we all decided to hike up a small mountain near my house for a leisurely family picnic.

While on the top of the mountain, Jo (my wife) took a few pics of us three Excel geeks.  As we were standing on a sloping mountain face this is how the pictures look.

Looking at the picture on left, you would confidently say that I am way shorter than other two. But picture on right tells a different story.

Avoid Hiring Boo-boos with Excel – COUNTIFS for the win [video]

Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.

This is because you are hiring a person for new temp role even before their current one ended. See above picture.

So how to avoid making such hiring boo-boos.

Simple, using Excel of course.
