1 Month from Today

One calendar month, not 30 days

A month is a calendar unit, so one month from today keeps the same day number whenever the next month has it. From 15 June the answer is 15 July. The number of days in between changes: it can be anywhere from 28 to 31.

When the day does not exist

Trouble starts at the end of the month. There is no 31 September and no 30 February. This calculator moves the result to the last day of the target month: starting on 31 January, one month later is 28 February (29 in a leap year), and from 31 August it is 30 September. Some organisations use a different rule, such as rolling over to the first of the following month, so confirm which rule applies if it matters.

Where it is used

Subscription renewals, monthly goals, lease and rent dates, and trial periods described as “one month”. If the wording says 30 days instead, use the 30-day page, because the results can differ.

Questions people ask

How many days are there between today and one month from today?

Between 28 and 31, depending on the month you start in. The page shows the exact number of days for today’s start date in the conversion table.

How should I handle monthly repeats?

Always calculate from the original start date, not from the previous result. Starting on 31 January, one month is 28 February. If you then add another month to 28 February you get 28 March, but two months from the original 31 January is 31 March. Chaining results makes dates drift earlier.
