No it is not zed. You brits and your grammar. Utterly insane. Just adding things for no reason. Color, favorite, zee, criticize. Lets get this right. No need to overcomplicate things. Simplify is the best policy
I don't think yanks who write month before day in dates should shout too loudly at others. I'm surprised you guys don't write time like this: mm:hh am/pm
Zed actually makes sense because of the letter C.
Oh and the word "solder", which you weirdos pronounce as sodder. Bonkers.
