To set a monthly reminder on iPhone, add a line in Reminders, tap i, turn on Date and Time, pick the due day and alert time, tap Repeat → Every Month, tap Done, then confirm the next date under Scheduled.

This is for you if rent, subscriptions, or admin tasks hit the same calendar date each month and you want one banner, not a fresh manual entry.

What guides already say

Apple Support, How-To Geek, and most bill blogs stop at the same four taps: new reminder, i, date, Repeat → Every Month. That part is right for a fixed date like the 1st or the 15th.

They rarely spell out the traps that make monthly lines feel broken:

  • The 9:00 a.m. default. Date without time leans on the global all-day setting. You think you picked evening; the banner fires at breakfast.
  • Day 31 in February. Every Month follows the calendar. A line on the 31st skips to the last day that exists in shorter months.
  • Every four weeks vs every month. Custom weekly intervals drift away from statement dates. Bills want calendar months.

Your takeaway: monthly repeat is one menu choice. The quiet system is time, list, and Scheduled proof.

Five taps, in order

  1. Name the line. Open Reminders, tap + New Reminder, type Pay rent or Submit timesheet.
  2. Open details. Tap i beside the title.
  3. Lock date and time. Turn on Date and Time. Pick the real due day (example: 1st) and a time you will act (example: 5:00 p.m.).
  4. Choose calendar month repeat. Tap Repeat → Every Month. For every two months or every three months, tap Custom, set Frequency → Monthly, then set Every to the interval you need.
  5. Prove and save. Tap Done, open Scheduled, and read the next fire date. If it is wrong, reopen i before you add more bills.

Your takeaway: if Scheduled disagrees with your head, fix it now, not on the 1st.

Walkthrough: Omar sets rent and a card on one Sunday

Omar pays rent on the 1st and his card on the 18th. He wants both on a Bills list, not mixed into Today.

  1. Park the list. He taps Add List, names it Bills, picks the wallet icon, then opens that list before adding lines.
  2. Rent line. + New Reminder → Pay rent → i → Date → 1st, Time → 5:00 p.m. → Repeat → Every Month → Early Reminder → 2 days before → Done.
  3. Note field. He taps Add Note and types Autopay Chase · confirm $1,650 posted so the title stays short on the lock screen.
  4. Card line. Repeats the same pattern for Pay Amex on the 18th at 8:00 a.m. with Every Month.
  5. Scheduled scan. He opens Scheduled, scrolls the next six weeks, and confirms rent shows on the 1st and the card on the 18th. Nothing else landed in Today unless the due date is actually today.

On the 30th he gets the early rent banner, moves cash, completes the line on the 1st, and the next month schedules without retyping. That Scheduled glance is the habit that keeps monthly repeats trustworthy.

When the date is not fixed

Some tasks belong to month-end, not day 31. Rent due on the last calendar day needs Repeat → Custom → Monthly → On the… → last → day, not Every Month on the 31st.

Our last day of month reminder guide walks that Custom branch. For several bills with early warnings and a Friday review, pair this page with the bill reminders PAY Lane walkthrough.

Divux on the Divux product page keeps calendar, tasks, and habits in one place so payday week sits next to focus blocks instead of buried in random lists.

Your takeaway: fixed date uses Every Month; true month-end uses Custom last-day.

Common mistakes (and the fix)

  • Leaving time off. You get a 9:00 a.m. surprise. Fix: reopen i and set an evening time you will actually open the banking app.
  • Picking day 31 for "end of month." February moves the ping. Fix: switch to Custom last-day, or pick the real statement date your bank uses.
  • Using every four weeks for rent. The alert drifts away from the 1st. Fix: Every Month on the calendar date, not a rolling week count.
  • Dumping six monthly lines into Today. The 1st feels like a guilt feed. Fix: one Bills list and a weekly Scheduled scan instead of living in Today.
  • Forgetting End Repeat on loans. A 12-payment plan should stop. Fix: i → End Repeat → On Date after the final month.

Your takeaway: most "broken" monthly reminders are wrong time, wrong repeat type, or wrong list.

FAQ

How do I set a monthly reminder on iPhone?

Open Reminders, tap New Reminder, type the title, tap i, turn on Date and Time, pick day and time, tap Repeat → Every Month, then Done. Open Scheduled to read the next alert before you close the app.

What happens if I pick the 31st for a monthly reminder?

Every Month follows the calendar. In shorter months the alert lands on the last day that exists, so February may ping on the 28th or 29th. For true month-end tasks, use Custom monthly with last day instead of a high fixed date.

Is every month the same as every four weeks?

No. Every Month keeps calendar dates like the 15th. A four-week Custom repeat rolls forward and slowly misses month-end. Use calendar month for bills; use week intervals only when you mean a strict rolling cadence.
