💎Planners

A date you need again next month is not a calculation

Everything else on this site answers a question and finishes. How many days until Christmas, what weekday 12 March 2031 falls on, how many working days a year holds — ask, read the number, close the tab. The answer is complete because the question was.

The tools on this page exist because some date questions are not complete. “When do I get paid” has no single answer; it has a cycle, and the useful output is the next fourteen dates rather than the next one. “When does this renew” is the same shape, and so is “which day does the ledger close”, and so is “when is my next shift”. In each case the thing worth holding on to is the rule, and the dates are what falls out of it.

That is the whole difference. A calculator takes values and returns a value. A planner takes a rule and returns a series.

Why an ordinary calendar entry is not enough

The obvious objection is that a phone already repeats things. It does, but only in three shapes — same date each month, same weekday each week, same fixed interval — and the recurrences people actually live with are frequently none of the three:

• The last working day of the month is not a date. It moves between three possible dates depending on how the month ends, and it is where payroll cut-offs and reporting deadlines sit.
• Twice a month is not every two weeks. One produces 24 dates a year and the other 26. A calendar app cannot tell them apart, and over a year the difference is two whole pay packets.
• The 31st does not exist in five months. Billing systems clamp to the end of the short month and go back afterwards; a repeating entry either skips or drifts permanently.
• A pattern that is not a multiple of seven rotates. Four-on four-off never keeps a weekday, and a month grid is exactly the wrong shape for reading it.
• An expiry date is not the deadline. For a passport under a six-month rule, the date to act on is roughly nine months before the one printed on it.

Each of those is a place where a repeating entry is not merely imprecise but confidently wrong, and wrong without saying so.

A rule for each shape of question

Money leaving on a rule. Bill and subscription due dates handles anything charged on a cycle, including the months where your date does not exist.

Money arriving on a rule. Payday countdown covers the four common pay cycles and the weekend rule that moves them backwards, which is the opposite direction to a bill.

Something that stops being valid. Renewal and expiry tracker counts to the date you have to act on rather than the date printed on the document.

A work pattern. Shift and rota planner rolls a weekly or fortnightly rota forward and shows where it drifts against the month.

A deadline defined by working days. Month-end close countdown finds the last Monday-to-Friday of each month, which is where close, payroll and filing deadlines land.

A date that comes round once a year. Anniversary and birthday planner lists a decade of them with the weekday on each, because the real question is usually which of those years falls at a weekend.

Free to use, no account

Every one of these runs in full without an account, computes in your browser, and sends nothing anywhere while you use it. That is the same deal as the rest of the site and it is not going to change: counting is free here.

Where a planner works with dates you care about, you can also ask for an email before one arrives, which is the only version of a reminder that helps: a renewal you are told about on the day has already cost you the thing you wanted to avoid. That is free too, takes nothing but an address, and one click in the email deletes it again.
