* In a Nutshell
The cron expression 45 17 1,15 * * runs Twice a month, on the first and fifteenth day, at 5:45 PM. Executing critical tasks on specific, predictable days of the month, like the 1st and 15th, ensures timely financial processing and avoids month-end contention. This cadence is vital for services requiring regular, predictable updates or billings.
* When to use this
Use 45 17 1,15 * * when a recurring task needs to run Twice a month, on the first and fifteenth day, at 5:45 PM. It uses Standard (5-Field POSIX) syntax, supported by Unix cron daemons, cloud schedulers such as AWS EventBridge, and container orchestration platforms such as Kubernetes CronJob.
CronBase parses 45 17 1,15 * * using a dialect-aware rules engine that identifies the Standard (5-Field POSIX) format, validates field structure against the Standard (5-Field POSIX) specification, and produces the translation above. Next run times are calculated by forward-scanning from the current UTC clock. Learn how CronBase works.
