scrollTo functiom for horizontal block

This is mockup of my app screen.
I have one block with 30 buttons(of every day in the month), it’s wide block with ion-scroll.
I need to scroll programitcally inside this block to the current day (as you can see in the mockup it’s day 23).

How should I do that?
I tried google about it and found only scrollTo vertical or jQuery solutions (which i don’t want)

Any idea someone?..
