What date is 15 days from today?
Counting forward 15 days from today gives the date below. Your own device does the arithmetic each time the page opens, so the answer is never stale.

Working it out from your device’s clock…
The date above is calculated on your own device when the page opens, from your device’s clock and time zone. Nothing is uploaded and no date is stored on this page.
Half a month, roughly but not exactly
Fifteen days is the usual stand-in for half a month, and it is a stand-in rather than an equal: half of a 31-day month is fifteen and a half days, half of February is fourteen. That is why semi-monthly pay is normally defined by the calendar (the 15th and the last day) instead of by a fifteen-day count — a fixed fifteen-day step would drift away from the month within a year.
The arithmetic behind the answer
Your browser reads today’s date from your device and adds 15 days, which gives the date above. The same date engine drives the date calculator, so the two pages cannot disagree with each other.
Every calendar day counts, weekends and public holidays included. Today is treated as day zero, so the result is the 15th day after today rather than counting today itself as the first day. If your contract counts the starting day as day one, shift the result by a day.
Because the answer depends on today, it is not written into the page. It is recalculated every time the page opens, in your own time zone, and never leaves the device.
Fifteen-day terms in invoicing and filing
Net 15 is the short end of ordinary invoice terms, used where cash flow matters more than goodwill: freelance work, small trade suppliers, deposits before scheduling. Fifteen days also appears as a common grace period on insurance premiums and loan instalments before a late charge is applied. Because fifteen days is an odd number of days, it always moves the weekday by one — a Monday start ends on a Tuesday.
What the count does not skip
Nothing is skipped here: weekends and public holidays sit inside the count, which is what a plain day count means in almost every contract, notice and policy. If your deadline is written in working days instead, 15 business days from today skips the weekends and lands later.
The result box still shows how the span divides — how many of the days are Mondays to Fridays and how many are weekend days — because that is usually the real question behind “will this be dealt with in time”. Public holidays are not deducted from that weekday figure.
Common questions
Is 15 days half a month? Only approximately. Months run 28 to 31 days, so fifteen days is slightly under half of most months and slightly over half of February.
What does Net 15 mean on an invoice? Payment is due fifteen days after the invoice date. This page counts fifteen calendar days from today, weekends included.
Does the weekday change over 15 days? Yes, by one. Fifteen is two weeks plus a day, so the result always falls one weekday later than today.
