You have a choice in life. You can accept certain things you cannot change. This one, you won't change. Even if you spearheaded a popular movement I doubt you'll get it changed. Everybody hates DLST and we still can't get rid of it.

So I suggest you adapt your language. You don't talk about the night of the fifth but the night from the fifth to the sixth. Three additional syllables in this case and the confusion evaporates quickly. You're focusing on the perceived problem and not on the solution. If you do resolutions for the new year, maybe add that point to your list.
