Recurring reminder-call prompts for ChatGPT

Not every reminder is daily. Some are weekdays only, some weekly, some every few days. ChatGPT can set all of them through ReminderIt, and it is worth understanding how your words translate into a schedule so you can phrase them well and check they landed correctly.

Weekday-only calls

For something tied to the working week, say the days plainly: "Call me every weekday at 8am Europe/London to check the team channel."

ChatGPT turns every weekday at 8am into a cron expression, 0 8 * * 1-5, where 1-5 means Monday to Friday. The call skips weekends automatically, so you are not woken on a Saturday by a workday reminder.

Weekly and specific-day calls

For once a week, name the day: "Ring me every Monday at 9am America/New_York to submit my timesheet." That becomes a cron pattern fixed to Mondays.

You can pick any day the same way, for example "every Saturday at 10am Europe/London to do the big shop." One day, one time, once a week, no fuss.

Custom intervals

Sometimes you want a gap rather than a weekday. For that, phrase it as an interval: "Call me every 10 days at 6pm Asia/Kolkata to change the water filter."

Here ReminderIt uses interval_days rather than cron, counting the days between calls instead of locking to a clock pattern. It is the natural fit for anything that repeats on a cadence rather than on set days.

How the translation works

You never write cron or intervals yourself. ChatGPT interprets your sentence and passes the right form to create_reminder: a cron expression like 0 8 * * 1-5 for day-and-time patterns, or interval_days for every-N-days cadences.

The practical upshot is that clear words matter more than syntax. Say the days or the gap, say the time, and always say the time zone.

Check it with list_upcoming

The best way to be sure a recurrence is right is to look at the next few calls it will make. Ask ChatGPT: "Show me my upcoming reminder calls." It uses list_upcoming to return the scheduled occurrences.

If the dates or times are not what you pictured, the recurrence or zone is off. Tell ChatGPT what you meant in the same chat and it will adjust the schedule, then you can check list_upcoming again.
