day() function in calculated fields / calculation properties

[03874]

We really need the integer day of a date to send some awesome, highly personalized emails. I'm not sure how it is that we could have two enterprise hubs 250+ calculation properties but not even a simple day() function. 

please help SOS!

Id like this or even just a day() function that can output the day of the month on a date property (similar to the year() and month() function).

If we have the day() function you can calculate the Day_of_Week easily

Definitely necessary to allow the same functionality as the Year and Month functions

Hallo, wir benötigen diese Funktion ebenfalls um einen Jahrestag (jährlich wiederkehrender Tag) aus eine, festen Datum ermitteln zu können.
Vielen Dank

Hello, we also need this function to be able to determine an anniversary (annually recurring day) from a fixed date.
Thank you very much

Super weird that calculated properties allows month() and year() but not day()
