It is Easter time. This is the first Easter we are celebrating in our new house. So it is bound to have so many special memories.

I had to share the enthusiasm with someone, so I made our first Easter egg hunt on the blog.
This year, join me on an Excel themed cryptic crossword clues – Easter egg hunt. Don’t forget to share your scores and explanations in the comments.Continue »

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.Continue »

Easter is around the corner. After what seemed like weeks of lousy weather, finally the sun shone today. I capitalized on the day by skipping work, walking kids to school, taking Jo out for some shopping, enjoying a leisurely walk / cycling with Nishanth in the park and almost forgetting about the blog. But it is dark now and before tucking the kids in, let me post a short but interesting home work problem.
Let’s say you are HR manager at Egg Co. and you are looking at the vacation plans of your team.
Easter is your busiest time and it would be a bummer if a majority of your staff are on leave during the Easter season (14th of April to 28th of April, 2017). So you want to know how many people are on leave. A snapshot of your data (table name: lvs) is shown above.
You want to answer below three questions:
- How many employees are on leave during Easter holidays (14th of April to 28th of April)?
- How many employees are on approved vacation during Easter holidays?
- How many employees in “Team ninja” are on approved leave during Easter holidays? Assume team employee numbers are in named range ninja
