How do you add widgets after 4.3 update?

[pcarr4]

This is my first post, so pls be gentle.
Since the 4.3 update, I can't figure out how to add widgets to my Sony Tablet Xperia Z.
In particular, I accidentally deleted the calendar widget and would like to have it back on the front page (not lock screen)
with my apps. I'd be grateful for any advice on adding/finding widgets

Anywhere on your home screen, press and hold for a moment and a side bar will appear, a list of things are in there, select widgets and find what you want. Simples.
