начать, начаться

начать, начаться - Could anyone please explain the differences in these two verbs and perhaps give some examples of their uses?

Thanks
Rob :oops:

начать - to begin, start
начаться - same but passive voice

Я начал новый день. -- I started a new day.
Новый день начался. -- A new day started

начать is a transitive verb

начаться is an intransitive verb
