**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.

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

*in*Excel Howtos

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.**

## How many employees are on leave during Easter holidays [Homework]

*in*Excel Challenges

*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.

** Click here to download the sample file**.

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**

Here is an interesting problem to keep your brain cells fight boredom on this Friday & weekend.

Let’s say you have some data like above.

Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? **To see seals** of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.

### 3 Seals Excel Puzzle

Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.

An Excel puzzle with 3 hidden seals.
