What does this cron expression mean?
Paste any crontab schedule to get a plain-language explanation and the next ten times it will run in your time zone. Standard cron has five fields: minute (0–59), hour (0–23), day of month (1–31), month (1–12 or JAN–DEC) and day of week (0–7 or SUN–SAT, where 0 and 7 are Sunday). A sixth leading field for seconds is supported too, as used by Quartz, Spring and node-cron.
