Hi everyone I would like to know how can we calculate time duration between two times my aim is to find time difference and see if its greater then the user would get a message saying YOU ARE LATE BY \_\_ HOURS \_\_ MINUTES . I wasnt able to find any api but I tried a workaround which just subtracted The time set by me and the current if its less than 1 report 1 hour late else report you are on time However this was working fine until let’s say my time to calculate from is 9:30 so if the current time is 10:00 it should return 1 hour but it’s saying 1 hour late so can anyone show me how to calculate time difference these are my blocks. ![Screenshot 2021-06-24 110419](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/9/7974bca195db55b76017eaa5a7bc58949c5b6063.png) ---

What is the source of the two times you want to check? Are the times being selected, or typed in or determined by the device’s clock? ---

Currently the time with which I want to check if he is late is is just in the blocks I.e 9:30 am and the other comparison time is the user’s current time. To simplify it is a attendance system which checks that if the user is late than the reaching time which is 9:30am warn him with a alert block saying if he is late by \_\_\_ hours \_\_ minutes ---

It is hard to understand what you are saying it is sounding too confusing, Can you please present your problem in a more clear way. ---

To simplify my statement I need to calculate duration between two given times one of which is the system current time ---

Hi there, You can view a project [here](https://x.thunkable.com/projectPage/60d44d1394ea3200113c32eb/) that will calculate the difference between a given start time and the current time. This project calculates the total minutes between the current time and the given start time. This is done by calculating `(difference in hours * 60) + (difference in minutes)` (Eg. if the event starts at 10.30 and it is currently 9.45, the total minutes = `(1 * 60) + (-15) = 45`) ![Screen Shot 2021-06-24 at 10.44.58 AM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/9/69b28c054e821df01a783f0cf8fd24a31fb64d97.png) If this is total number of minutes is 0, it says that the event is starting right now. If this is greater than 0, it says that the event starts in X hours and Y minutes. If it is less than 0, it says that you are late! The event started X hours and Y minutes ago. (X = total minutes divided by 60, Y = remainder of total minutes divided by 60). ![Screen Shot 2021-06-24 at 10.45.28 AM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/c/ec3d9bfd9de9ca00541793cefbc48b3d7a9b43b1.png) ---

I simply use a Google sheet having 3 columns start time end time result (sheet calculation of end time - start time) In my code, I update start time and end time and read result. It always works and the code becomes simple. ---

Thanks @muneer for another solution, It’s a good idea but I want this to be an offline feature ---
