Date counter help

I have a project here that I wanted to add the age of an animal to. Example: I choose a date and the app shows me how many days, months or years the dog has, and each information would have to be said separately, counting the days, when the days reached 30 or 31, shows the months and when reaching the end of 12 months, shows the year.

I tried to do with the clock blocks but I still have a lot of difficulty in this part hehe

Can anyone help? With some block scheme, extension or idea.

First you can get the Duration between two times in milliseconds using this Block.

Then you can convert that Duration to Seconds, Minutes, Hours, Days and Weeks.

And Afterward with little Logic and Efforts you can Get the Years.
