Sometimes we need to count time difference when participating a contest or an exam, and if the time difference (between start time and end time) is greater than certain time, participants are failed in the contest. So, in this situation we need to know the method to compare time difference with certain time. This article will introduce you a quick method to fix this issue.

**Precondition:**

Prepare a table record the start time and end time of a contest. And if time difference is greater than 2 hours, participators fail the contest, on the other side, if time difference is less than 2 hours, they pass the contest. We need to enter PASS or FAIL in column C.

**Method: Compare Time Difference with Certain Time in Excel**

**Step 1:** In C2 enter the formula **=IF(B2 > A2 + TIME(2,0,0),”FAIL”,”PASS”)**. In this formula, if B2 is greater than A2+2 hours, then formula returns **FAIL**, otherwise it returns **PASS**.

**Step 2:** Drag the fill handle down to fill B3:B6. Verify that B3:B6 are filled with **FAIL** or **PASS**.

We can see that in this example, only two people pass the contest.

**Comment:**

- As
**TIME(HOUR,MINUTE,SECOND)**, so we can change hour/minute/second values per our real demands. If we want compare time difference with 2 hour 5 minutes 10 seconds, we can update the formula as =IF(B2 > A2 + TIME(2,5,10),”FAIL”,”PASS”).
