For DeepL:

-> À trois heures et demie

-> 14 h 30 du soir,

-> À 14 h 30,

-> On va au cinéma à 14h30.

Correct for everything but the first, not sure why it added "du soir". For the a complete sentence "Um halb drei gehen wir." it's also correct ("On part à 14h30.").

As far as I can tell it's _in_correct in every instance except the first:

  À trois heures et demie = À trois heures et demie

  Aller à deux heures et demie =\= 14 h 30 du soir [1]

  A quatre heures et demie nous partons =\= À 14 h 30 [2]
 
  A trois heures et demie nous allons au cinéma. =\= On va au cinéma à 14h30 [3]

[1] misses the "to go" part and also gets the time of day wrong- which is important because it uses 24-hour clock notation (and so it's obvious that it has no idea what 14h30 means).

[2] completely misses the action ("nous partons") and gets the time wrong ("quatre heures" is "four o'clock", not 14).

[3] Still gets the hour wrong (14h30 to "trois heures", i.e. three).

You'd certainly wouldn't want those translations to "help" you with your appointments in France, or Germany.

I was only referring to the time. "halb drei" is two thirty, which usually means 14:30 unless you specifically say "in the morning". The action in [2] would probably be added if you add a full stop.

[YeGoblynQueenne]

The time is also wrong, in three out of the four cases above.

No, the 3rd one is 4:30 not 14:30. Quatre, not quatorze.

[rconti]

and the 4th one is 3:30. I'm also not sure why you introduced "afternoon" into this; it's not said anywhere and it's easier to understand the translation if you just pretend like this is all early in the morning.
