This is a very charming illustration and I do approve of Accidental Latin, but unfortunately, that is not what this (Fake) Accidental Latin actually says. Google Translate seems to think "temu" is identical to "timor" (infinitive, "to fear"), which would then be conjugated in first-person singular as "timeo" ("I fear"). "Temu" is not a word in Latin. So that is a very weird leap on Google Translate's part to turn gibberish into... something vaguely etymologically similar sounding? Hmm.
Next, "die" does mean "day," though nominative singular is "dies," i.e. "dies irae." It could be conjugated "die" if it was in ablative or locative case, but "die ad die" would mean something more like "day to day." "Ad" is in a "to" direction and "ab" is from, i.e. "ab urbis," and ablative case is used to indicate the movement of a thing. In short, "by" is not really a way to translate "ad"; we might want "per" here? (Through, by means of, etc.)
Not to mention, it would be weird to put one "die" at the start and another at the end The verb also usually goes at the end in Latin sentences, just for that extra bit of fun. So yes, in short, this is not actually Latin, and Google Translate is very bad at Latin in particular. Nonetheless, still charming.
