I'm taking this online course on technical writing. It suggests that you can omit "on" from

The meeting happened on Monday

to turn it to

The meeting happened Monday

The second one seems wrong to me, and I haven't seen it being commonly used either.

  • Why should it "seem wrong" just because it's less common? – Kris Aug 9 '18 at 6:30

    As a British English speaker I would be much less likely to omit the "on" when talking about the past than when talking about the future. For example I would almost always say "I was talking to John on Monday" but would quite commonly say "I'll see you Monday, then". Having said that it's very informal and I would be unlikely to write it down. I would also be less likely to omit the "on" when speaking of a place or an event. "I'll be in Lincoln Monday" or "My car's in for service Wednesday" are used but are less common than "I'll see you Monday". – BoldBen Aug 9 '18 at 7:39
  • I have seen many times, news and media do gramatical mistakes. So i would not rely on them for learning english. Rather strictly viewing by gramatical sense, is omiting certain words correct? – Fennekin Aug 9 '18 at 9:08
