Hi, hope you can help. I have a table with 19 columns (and 50k + rows) which changes 3 times a week. One of the columns is times. I need to divide this where there is at least a 20 minute gap from the row above. I was thinking of identifying in a new column T eg 1, 2, 3 etc but having trouble getting it to work.

On the table below, Row 2 & 5 could be group 1, Row 3 & 8 could be group 2 etc. An added complication is there can be no more than 6 in each group.

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.

Hi, Could you please share a sample result sheet? I didn't get where to write the newly created groups.
Is VBA ok?

Hi, there wasn't a specific format yet as it's a new project I'm working on. Just grouped with 20 mins between them.

VBA is fine.

Even numbering them in groups in Column T would be a great help for now. Then I could sort or filter and move it manually if necessary.

Thanks

I manually created the sort of result that would be OK. Essentially it's for sharing work out but they need a 20 min gap to complete and move on. On this example, I'd need 7 people.

Not really, that's just the current table format. It only contains the date that is provided as well in column G. However, I can't change the format so every update would come in like that and would need to be adjusted to suit.

I think this should work. T2:
Excel Formula: 
=IF(COUNTIF(G2:G$18,"<="&G2+TIME(0,20,0))>6,6,COUNTIF(G2:G$18,"<="&G2+TIME(0,20,0)))

I'm getting the result shown in column U. It's very close, but if 6 was a person, they wouldn't be able to complete all those tasks in time

Oh OK. Maybe I didn't explain it well. These are all jobs that I need to divide up. Each job takes 20 mins.

So the person doing 0600 in G2 cannot do something else until 0620 in G5. Another person needs to do G3 and then free to do G8 and so on. So wanted to number them as person 1, person 2 etc. Then I can sort that column.

Open to other suggestions if you think of any other way.
