How to quickly add hours/minutes/second to date and time in Excel?
For instance, you have a list of dates and times in a worksheet, and now you want to add the same hours/minutes/seconds to these cells which are mixed with date and time. You can use formulas to solve this task, but here I can tell you another trick to quickly attain this goal in Excel.
Using formulas to add hours/minutes/seconds to datetime
Using a handy tool to add hours/minutes/seconds to datetime
In Excel, generally, you may use the formulas to add hours, minutes or seconds to the datetime cells.
1. Select the cell next to the first cell of the datetime list, and then type this formula =A2+1/24 into it, press Enter key and drag the auto fill handle over the cell needed this formula. See screenshots.
2. Then right click to select Format Cells from the context menu. And in the Format Cells dialog, under Number tab, select Custom from the Category list, then type m/d/yyyy hh:mm:ss into the Type textbox. See screenshots:
3. Click OK. Then you can see each date and time cell is added one hour.
1. If you want to add one minute to cell, use this formula:=A2+1/1440, if you want to add one second to cell, use this formula: =A2+1/86400.
2. In above formulas, 1 indicates to add one hour or one minute or one second, you can change it as you need.
3. If you want to add hours, minutes and second to a date simultaneously, you can use this formula =A2+TIME(23,23,34), this means to add 23 hours, 23 minutes and 34 seconds to a date cell. But with this formula, you cannot add time over 24 hours.
