Final answer:
To find the time between two dates, the DATEDIF function is used. It calculates the difference in days, months, or years. DATE and TIME functions are for creating values, and WEEKNUM finds the week number.
Step-by-step explanation:
If you want to find the time between two dates, you would use the DATEDIF function. The DATEDIF function is designed to calculate the difference between two dates in days, months, or years. The options provided in the question are 1) DATE, 2) TIME, 3) DATEDIF, 4) WEEKNUM. DATE and TIME functions are used for creating date and time values respectively, not for finding the difference between them, while WEEKNUM is used to find the week number for a given date.
For example, if you have two dates, such as January 1, 2021, and March 1, 2021, and you want to calculate the number of days between them, the DATEDIF function can be used in a spreadsheet application to do this. You would input the starting and ending dates as arguments in the function, along with "d" to signify you're looking for the number of complete days between the two dates. This function simplifies the calculation of time periods, whether for educational purposes, project planning, or other various applications.
