How do I calculate months from today?

Keep the same day of the month and move the month forward. When the target month is shorter — for example adding one month to January 31 — the date clamps to the last day of that month (February 28 or 29), which is the standard convention used by contracts and this calculator.

What date is 3 months from today?

Set the slider to 3 and the exact date appears above. Three calendar months is not the same as 90 days: depending on which months are in the range, it can be anywhere from 89 to 92 days. Use months for month-defined terms (rent, subscriptions), and days for day-defined terms.

Why is a month from January 31 not March 3?

Some simple calculators overflow short months: January 31 + 1 month becomes February 31, which rolls into March 2–3. Legally and practically, one month from January 31 is the end of February. This calculator clamps to the last day of the month, matching that convention.

📌 Month lengths differ, so the day is kept where possible: adding one month to January 31 gives the last day of February, not March 2–3.

Calendar months vs. days

A calendar month is a variable unit — 28 to 31 days — so month-based and day-based deadlines drift apart quickly. Six calendar months is between 181 and 184 days, while “180 days” is a fixed span. Subscriptions, leases and loan terms usually run in calendar months; legal and medical windows are often defined in days. Match the unit to the wording: for day-defined terms use the days from today calculator (for example 180 days from today), and for longer horizons years from today.
