When it runs next
What it means
Minute 0 and hour 0 pin the time to 00:00, and the three asterisks let it run on every day of every month. Midnight means midnight on the server's clock, which is usually UTC on cloud machines, so check before assuming it lines up with your own evening.
To run once a day at another time, change the first two fields: 30 6 * * * runs at 6:30 every morning. Try not to put important daily jobs between 1:00 and 3:00 in a time zone with daylight saving, because that hour can be skipped or repeated when the clocks change.
