BRev Cron builder
Cron: every hour — 0 * * * *
The 0 pins the minute, the * opens every hour: one run per hour, exactly on the hour. The @hourly macro is shorthand for the same thing.
The classic mistake is writing * */1 * * * and expecting hourly — the minute field is still *, so it runs every minute of every hour. The minute field must be a fixed value for an hourly job. And since half the internet schedules at :00, consider 17 * * * * — same cadence, no top-of-hour stampede against your own database.
