# Add hours to a time

You can add (or subtract) a number of hours from a time using fractions.
Dates are represented as sequential whole numbers so 1 hour is equivalent to the fraction (1/24).
Times are represented as fractions based on there being 24 hours in a day.
1 Hour is 1/24 = 0.04166
1 Minute is 1/(24*60) = 1/1440
1 Second is 1/(24*60*60) = 1/86400

### Example

 A 1 =TODAY() = Saturday 01 June 2024 2 =NOW() = Saturday 01 June 2024 06:36:09 3 =A2 + (6*(1/24)) = Saturday, 01 June, 2024 12:36 PM 4 =A2 + TIME(6, 0, 0) = Saturday, 01 June, 2024 12:36 PM 5 =A2 + (8/24) + (15/1440) = Saturday, 01 June, 2024 02:51 PM 6 =A2 + TIME(8, 15, 0) = Saturday, 01 June, 2024 02:51 PM 7 =A2 + (13/24) + (25/1440) , (45/86400) = Saturday, 01 June, 2024 08:01 PM 8 =A2 + TIME(13, 25, 45) = Saturday, 01 June, 2024 08:01 PM
