Rules this tool follows

• Standard 5-field syntax: *, lists 1,15, ranges 1-5, steps */10 and 8-18/2, month and weekday names (jan, mon), and 7 as Sunday.
• If both day-of-month and weekday are restricted, a run happens when either one matches. This is the classic Vixie cron rule, described in the crontab(5) manual page. Some schedulers (for example Quartz or AWS) use other syntax and are not covered.
• Shortcuts @hourly @daily @weekly @monthly @yearly are expanded for you. Everything runs in your browser, nothing is sent anywhere.
• Daylight saving changes are handled by your device's clock in "This device" mode; a daemon may skip or repeat a run at the switch. I did not fetch a source for that behaviour, so check your scheduler's docs.
