You'll also get zero records from this, unless you've changed SQL Server's implicit cast. Try LIKE 'Jan % 2018%'
I've never had issues with BETWEEN using datetimes and paremeterized queries. FWIW. If ticks ever did become an issue, I'd follow your mechanism re date, incrementing the upper boundary and using < if necessary.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
