ICS file generator

Fill in the event and download an .ics file that opens in Outlook, Apple Calendar, Google Calendar and every other calendar app — or copy an add-to-calendar link.

What an .ics file is

An .ics file is a small text file in the iCalendar format (RFC 5545). Every major calendar understands it, which makes it the simplest way to share an event without asking people to sign up for anything — attach it to an e-mail, link it from a website, or add it to a newsletter.

Time zones done right

Pick the zone where the event takes place, not where your guests are. A single event is saved in UTC, so a 2 pm New York meeting shows as 7 pm in London and 4 am the next day in Seoul automatically. Repeating events are saved with the zone name instead, so a weekly 9 am stand-up stays at 9 am local time when daylight saving time starts or ends.

How to add the event

Outlook (desktop)

Double-click the .ics file and click Save & Close, or drag it onto the calendar.

Apple Calendar (Mac, iPhone)

Open the file; Calendar asks which calendar to add it to. On iPhone, tap the attachment in Mail.

Google Calendar

Use the Add to Google Calendar button above, or Settings → Import & export → Import on a computer.
