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.
Nearest second: =TIME(HOUR(A1), MINUTE(A1), SECOND(A1)).
- SECOND formula rounds up any fractions and returns full seconds.
Nearest 15 seconds: =TIME(HOUR(A1), MINUTE(A1), MROUND(SECOND(A1),15))
- Use MROUND() to round up seconds values to nearest multiple of 15 (or whatever else)
Nearest Minute: =TIME(HOUR(A1), MINUTE(A1)+(SECOND(A1)>30),0)
- The seconds value will always be zero. We just look at fractional minutes portion to see if they are more then 30 to round up to next minute. The trick is to add up Boolean check (SECOND(A1)>30) to minutes value.
Nearest 15 minutes: =TIME(HOUR(A1), MROUND(MINUTE(A1)+SECOND(A1)/60,15),0)
- This one uses MROUND to round total mins (including fraction) to nearest multiple of 15.
Nearest 37th minute: =TIME(HOUR(A1), MROUND(MINUTE(A1)+SECOND(A1)/60,37),0)
- Same logic. Just to show you how to round to an arbitrary minute.
Nearest hour: =TIME(HOUR(A1) +((MINUTE(A1)+SECOND(A1)/60)>30),0,0)
- Check if total minutes is greater than 30 and add the result to hours.
Time for some home work
Let’s test your timing skills. Assuming A1 has date & time value (like 26-Jun-2017 7:21:32 AM), round it up to nearest working hour.
- The working hours are 9AM to 6PM on weekdays (Monday – Friday)

Pivot Table will involve manual intervention; hence I prefer to use the 'countif remove duplicate trick' along with 'text sorting formula trick; then using the offset with len to name the final range for validation.
if using the pivot table, set the sort to Ascending, so the list in the validation cell comes back alphabetically.
Hui: Brillant neat idea.
Vipul: I am intrigued by what you are saying. Please is it possible to show us how it can be done, because as u said Hui's method requires user intervention.
Thks to PHD and all

Table names dont work directly inside Data validation.
You will have to define a name and point it to the table name and then use the name inside validation
Eg MyClient : Refers to :=Table1[Client]
And then in the list validation say = MyClient
Kieranz,
Pls download the sample here http://cid-e98339d969073094.skydrive.live.com/self.aspx/.Public/data-validation-unsorted-list-example.xls
Off course there are many other ways of doing the same and integrating the formulae in multiple columns into one.
Pls refer to column FGHI in that file. Cell G4 is where my validation is.
Vipul:
Many thks, will study it latter.

[...] to chandoo for the idea of getting unique list using Pivot tables. What we do is that create a pivot table [...]
@Vipul:
Thanks, that was awesome! 🙂
@Playercharlie Happy to hear that 🙂
Great contribution, Hui. Solved a problem of many years!
Thanks to you, A LOT
Hi Hui,
Greeting
hope you are doing well.
I'm interested to send you a private vba excel file which i need to show detail of pivot in new workbook instead of showing in same workbook as new sheet.
Please contact me on muhammed.ye@gmail.com
Best Regards
