This calculation is the heart of the whole operation. Also, let’s set the storage type to “unstored”. Reminder: the first thing we do when we define a calculation field is, of course, make sure the result type is correct: in this case we want the result type to be text. Now that we understand the design of a minimal “ics” file, we can define a calculation field, ical_basis, in our database to assemble and format the data accordingly. So, let’s add a UID field (auto-enter, text) and a UTC offset field (global, number). That’s right… if an appointment changes in your database, you can export it, and reimport it into your calendar without having to worry about duplicates.

The UID is very important, because if you import the same appointments more than once, the calendar will be smart enough to update existing entries where there is a matching UID, rather than allowing them to appear twice. But as long as it’s unique within your calendar, you’ll be fine. Ideally it’s some form of “ UUID” which means that heroic measures have been taken to attempt to guarantee its absolute uniqueness.
What is ical export serial#
Since I don’t care about that, I’m just making it the same as DTSTART.Īnd finally we come to the UID entry, which is simply a unique serial number. During Daylight Savings Time, the offset value would be -7, but we’re on Standard Time now, so the correct value is -8.Ĭlearly DTSTART is the beginning time for the appointment, and DTEND is the ending time, but what’s DTSTAMP? That is the “creation time” of the appointment, and apparently is required. So the first row in our appointments table, with a starting time of 10:00 Am, will be converted to the UTC equivalent of 180000 when we export it, because the database is located in the Pacific time zone, which is 8 hours offset, i.e., UTC-08. One important observation about the time portion: it is represented as UTC time, not local time. First we have the date formatted as YYYYMMDD, followed by a T, followed by the time in 24hour format, hhmmss, followed by a Z. The BEGIN, SUMMARY and END entries seem self-explanatory, but what’s going on with those “DT” entries? Well, as you’ve probably guessed, they’re timestamps. Let’s take a closer look at the body section. Next we have one or more body entries that look like this:Īnd at the very end of the file comes the footer, which looks like this: PRODID:-//FileMaker Pro//NONSGML yourSolutionNameHere//EN At the beginning of the file is the header, which looks like this: We’re going to create an “ics” file, which is a text file with three distinct elements. Let’s start with a basic table of appointments, like this. I don’t claim that what follows is in any way authoritative, just that it works… and not just with iCal, but with Outlook, Google Calendar and any other program that recognizes the iCalendar format. I’d never done this before, but I did a bit of reading on Wikipedia and elsewhere, and it turns out to be fairly straight forward. If you're using a Google Account for work, school, or other organization, your admin might've changed the sharing settings for your calendar. If you can't find the Secret address, ask your admin for help.The other day I needed to export some appointments from FileMaker to iCal. If you accidentally shared your calendar's Secret address, click Reset to create a new Secret address. Do not share this address with other people. Important: Only you should know the Secret address for your calendar.
In the "Secret address in iCal format" section, copy the link.On the left panel, under “Settings for my calendars,” click the name of the calendar you want to use.

If your calendar application doesn't have a full sync option, or if you want a read-only view of one calendar, you can sync your calendar to the application using a link to iCal.
