## RANDBETWEEN – Excel Function

What it does: The RANDBETWEEN() Function generates a random number between two integers.

Plain English: Rather than generating a random number between 0 and 1, RANDBETWEEN() generates an integer between a given range of integers that you provide. For example, you may want to pick 6 random lottery numbers between 1 and 35. This formula could help generate those.

Arguments: RANDBETWEEN(lower number, higher number)

• Lower number – the lowest integer possible you want to generate
• Higher number – the highest integer possible you want to generate

## Dates in Excel – Part 1

Excel is very good when it comes to dealing with dates. To simplify the math on its end, it calculates a date as “the number of days since January 1, 1900.” Let’s look at an example: Believe it or not, these are actually the same date. The only difference is that B2 is formatted as a date, while D2 is not.

Since dates are calculated by Excel so easily, finding the difference between two dates is easy as well. After putting March 5th into cell D2, I created a formula in F2: “=D2-B2”.

That’s it! We now have the total number of days in between those two numbers. ### Dates and Times Let’s look at this problem. We have 9 racers who all started at 10:30am. They finished at very different times. We tried to quickly check their race times using a simple subtraction formula, but we get an error. This is because the times are not formatted in a proper date format. Using Text to Columns, we separate the “PST” from the rest of the format. Next, we’ll make sure columns G and I have proper time format: • Delete Columns H and J
• Change formatting on (now) Column I • Select Custom format and “hh:mm:ss”. As you can guess, this formats the result in hours, minutes, and seconds. We can now see how long it took every member of the race to finish.
