Do you use 'til or till?

<p>I don’t know which I should use… In case you’re wondering, there’s no right answer. Till came first, then until, then 'til.</p>

<p>I always thought 'til is right and till is wrong because I thought it is a contraction of until. Interesting to learn that until evolved from till.</p>

<p>Till, but I’d normally just say “until.”</p>
