Add Time Slots In Excel
How to group time by minutes or hours intervals in Excel?
Here is a list of time, and what I want to do is to group time by 3 hours as below screenshot shown, how can I quickly solve it in Excel?
Say you need to create regular appointment slots for a doctors surgery from 8 am to 12 noon, or times for interviewing job applicants. It’s really easy to auto create a list of available appointments with the Excel Auto Fill feature. All you need to do is enter your first two appointments, in this case. Bringing Time Slots Into The Game. Things get slightly more complicated when, in addition to a date picker, you also need to provide a time-slot picker. The easiest way to achieve time selection would be by providing an extra input field as a step after the date has been selected. The reason for that is ‘Time’ is still a numeric value. However, it’s stored differently. The value 39:00:00 is converted to 1.63 or roughly a day and a half. Excel automatically converts 24 hours into 1. To remedy this, multiply the ‘Time’ value first by 24 before multiplying it by 19. This is how you convert time to decimals in Excel.
Group time by hours intervals
To group time by hours interval, you just need one formula.
Select a cell next to the time, and type this formula =FLOOR(A2,'3:00'), A2 is the time you use, 3:00 is the hours interval, press Enter key and drag fill handle down to apply this formula to cells.
Group time by minutes intervals
If you want to group time by minutes intervals, also can use formulas.
Select a cell next to the time, and type this formula =FLOOR(A2,TIME(0,15,0)), A2 is the time you use, 15 is the minutes interval, press Enter key and drag fill handle down to apply this formula to cells.
Tip: if the formula results are displayed as digits, just need to format them as time format.
