Cron @daily — Run Once Per Day

The @daily shorthand (also @midnight) is equivalent to the cron expression 0 0 * * * — it runs a job once per day at midnight (00:00).

This is one of several convenient shorthands supported by most cron implementations:

• @yearly / @annually = 0 0 1 1 *
• @monthly = 0 0 1 * *
• @weekly = 0 0 * * 0
• @daily / @midnight = 0 0 * * *
• @hourly = 0 * * * *

The shorthands are clearer and less error-prone than writing out the full expression, but they don't allow customizing the time (e.g., you can't use @daily to run at 3 AM).
