Hi
Kat,
To
round time down to the nearest half hour, you can use the following formula:
Code:
=TIME(HOUR(A1),FLOOR(MINUTE(A1)/30,1)*30,0)
Assuming your time values are in column A, you can enter this formula in cell B1 and drag it down to apply it to all the cells in column B. This formula uses the
HOUR function to extract the hour value from the time, the
FLOOR function to round down the minute value to the nearest half hour, and the
TIME function to combine the hour and minute values with 0 seconds.
To
set up a pivot table to group your data by half hour chunks, you can follow these steps:
- Select your data range, including the column headers.
- Go to the "Insert" tab and click "PivotTable".
- In the "Create PivotTable" dialog box, make sure the "Select a table or range" option is selected and that your data range is correctly displayed.
- Choose where you want to place your pivot table and click "OK".
- In the "PivotTable Fields" pane, drag the column containing your time values to the "Rows" area.
- Right-click on any of the time values in the pivot table and select "Group".
- In the "Grouping" dialog box, select "By" and choose "Number of Days", "Number of Months", or "Number of Years", depending on how you want to group your data.
- In the "By" field, enter "0:30" to group your data by half hour chunks.
- Click "OK" to apply the grouping.
To
change 24 hour time to 12 hour time in Excel, you can use the following formula:
Code:
=TEXT(A1,"h:mm AM/PM")
Assuming your 24 hour time values are in column A, you can enter this formula in cell B1 and drag it down to apply it to all the cells in column B. This formula uses the
TEXT function to convert the time value to a text string in the format "h:mm AM/PM", where "h" represents the hour in 12 hour format, "mm" represents the minute, and "AM/PM" represents the time of day.
