"The work starts on Monday."
But sometimes I see は after a time expression like 今日は, When would you use は and when に?
Thank you for clarifying. I watch a lot of Japanese programming and I usually don't hear the に so I was a little confused if it was necessary..
The "te" form in "hajimete" is derived from "hajimeru" whereas the "ri" form is from "hajimari".
"Hajimeru" is a transitive verb thus requires an object. "Hajimaru" is an intransitive verb and does not require an object.
Examples are, I will start the class = Watashi wa kurasu o hajimemasu. The class will start = kurasu ga hajimarimasu.
After having gotten flagged incorrect on too many occasions for missing "the" (despite no such thing in the Japanese version of sentences), I would very much like to flag Duo as incorrect for missing その or some such from the Japanese here.
