TIME conversions in Microsoft Excel.
We’ve covered a lot of ground with posts on date calculations in Excel: using the DATEDIF function, calculations without the DATEDIF function , and in the most recent post – business day calculations with the NETWORKDAYS funtion. Now it’s turn to perform some TIME conversions and calculations in Excel. We will use TIME, TIMEVALUE, NOW, HOUR, MINUTE, SECOND, TEXT, and MOD functions to perform various time operations…
NOW function displays the current date and time. Depending on your cell formatting, it might be date only, or if your cell format is General, it could even be serial number equivalent of your current date and time. While this function has no arguments, its syntax still calls for a set of parenthesis: =NOW(). We already know that Excel uses the whole value of 1, in reference to the “beginning of time”, as far as Microsoft is concerned – January 1, 1900. Similarly, today’s date has the value of 42,124 The decimal point value references the fractional time portion of any date. As an example, 0.5 denotes NOON, while 0.75 refers to 6 PM. [0.75*24 = 18] Similarly, one minute, is 1/60th of an hour or 1/1440th of a day, calculating to be 0.069(4). Keep in mind that, whenever date/time value starts with a 0, the date portion has no value, and we are working with the time value only.
