Create Calendar Entries with Anthropic Claude 3.5

A few days ago, my jazz piano teacher sent me the new fall/winter schedule for my private jazz piano lessons — 13 different dates — as a JPG (mine are outlined in green marker):

I was too lazy to go make 13 entries in Google Calendar, so I decided to see if Claude could help me out:

I first uploaded the jpg to Claude 3.5 Sonnet)…

My prompt: List the dates that are outlined in green

The dates outlined in green in the image are:

Friday, 13-Sep-24 Friday, 27-Sep-24 Friday, 11-Oct-24 Friday, 8-Nov-24 Friday, 6-Dec-24 Friday, 20-Dec-24 Friday, 17-Jan-25 Friday, 31-Jan-25 Friday, 28-Feb-25 Friday, 14-Mar-25 Friday, 11-Apr-25 Friday, 25-Apr-25 Friday, 23-May-25

These dates correspond to the Friday column for students who have their first every-other-week lesson starting the week of Tuesday Sept 10, 2024.

Cool – that was easy and accurate. Now I need to get it into my calendar, so I asked it to create an ics file…

My prompt: Create a calendar ics file that creates an appointment on each of those dates at 2pm pacific time. The appointment title will be “Jazz Piano Lesson”

Certainly. I’ll create an ICS (iCalendar) file with appointments for “Jazz Piano Lesson” on each of the dates you specified, set for 2:00 PM Pacific Time.

I’ve created an ICS file with the following details:

1. Each event is titled “Jazz Piano Lesson”

2. The events are scheduled for 2:00 PM Pacific Time on each of the specified dates

3. Each event is set to last for one hour

4. The time zone is properly adjusted to UTC (Z) in the file

5. Unique identifiers (UIDs) are provided for each event

You can save this content as a .ics file and import it into most calendar applications. Here are a few notes about the file:

1. The times are in UTC (Coordinated Universal Time). 2:00 PM Pacific Time translates to 9:00 PM UTC (21:00) for dates not in Daylight Saving Time, and 10:00 PM UTC (22:00) for dates within Daylight Saving Time. The file accounts for these changes.

2. The DTSTAMP for all events is set to the date of this conversation (August 24, 2024) as a placeholder. Your calendar application will likely update this when you import the events.

3. The UID for each event is unique, based on the date of the lesson and a simple string.

To use this file:

1. Copy the content of the artifact

2. Paste it into a new text file

3. Save the file with a .ics extension (e.g., “jazz_piano_lessons.ics”)

4. Import this file into your preferred calendar application

Most calendar applications should be able to read this file and create the appropriate recurring events. Let me know if you need any modifications or have any questions!

I went to calendar.google.com, imported the ics, and my appointments were imported perfectly!
(To import ics files into Google calendar, go to the calendar settings, then to import/export)

I’m pleasantly surprised at how easy this was!

I tried the exact same thing in ChatGPT — it identified the dates in the images, but it was unable to create an .ics file. However, it did give me some Python code to create the ics file for me.
