Midnight daily is where backups, log rotation, and report generation traditionally live. The @daily shorthand is exactly equivalent to this expression.
Two practical notes: first, midnight is server-timezone midnight — a UTC server means 00:00 UTC, which is early morning in most of Europe and evening in the Americas. Second, midnight is also when everyone else's heavy jobs run; moving yours to 0 3 * * * often makes the same work finish faster.

FAQ
Midnight in which timezone?
Whatever the host considers local — typically UTC on cloud servers. Verify with date on the box, and prefer UTC schedules for deterministic behavior.
Is @daily exactly the same?
Yes: @daily expands to 0 0 * * *. Use whichever reads better in your crontab.
What if the server is down at midnight?
The run is skipped — cron does not catch up. For must-run daily jobs (billing, retention), have the job itself check its last-run timestamp, or use anacron / a scheduler with catch-up semantics.
