Firstly we concatenate the year of our passed in date+1 to the passed in starting month and day 4 as an argument to the convert function to get a valid datetime value that we know is somewhere in week one for that year. In this article I will be looking at the three main date functions DATEADD, DATEPART and DATEDIFF (there is a fourth called DATENAME but I want to get to the end of this article before you fall asleep so I decided to leave it for another date and time! And no it doesn't foretell the name of your future blind date so it's not as interesting as it sounds anyway) Then I will be combining all three in a user defined function of our own by which time our necks will be well and truly stretched!"

Date fields are not compatible between Windows and Mac versions of Excel; if you create a spreadsheet with date fields on one platform and open it with the other, the date values will be incorrect
Why not use the same logic to calculate the difference for the time units in the timestamp values? The reason is that when you get down to the time units, the difference between two timestamps might be higher than an integer can hold. The task is to correctly calculate the differences between the timestamp pairs, considering all possible datetime units, and produce the desired result that Table 2 shows
