Hi,

I have these 2 time stamps. the sum of working hours is over 24h.

11/1/2023 7:33:46
11/2/2023 8:55:07


To calculate total hours I use formula: WORKDAY(F1,H1)+MOD(H1-F1,-1) but then if it is over 24h it calculates as 1:21:21

Any help to fix this is appriciated :)

Hey there, I am a beginner Excel user. I am trying to understand the use of double quotation mark for duration of time in formulas. Double quotation converts the numbers to text, right? But I am able to use it and it says as numbers in this formula; let's say there is 20:00:00, and I want to substract this from 30 hours. My formula would be ="30:00:00"-A2 and it works perfect! So here double quotation doesn't convert it to text. However, when I use double quotation in an IF formula inside a calculated field in pivottable, it doesn't work. For example: =IF('Field 1'>="1:00:00",1,0) Could you please explain and help me understand why I can not use double quotation in the if formula but I can use it when I substract it? I have been trying to understand this for 3 days... Going crazy. Thanks al lot...
