Calendar Generator
/install ics-generator
ics‑generator
When to use
When you need to convert a schedule, study plan, or task list into an iCalendar (.ics) file that can be imported into Google Calendar or any other iCalendar‑compatible client.
Workflow Overview
-
Collect structured events – each event must contain: -
summary(string) -description(string, optional) -start(ISO‑8601 date/time or JSDate) -end(ISO‑8601 date/time or JSDate) -colorId(Google Calendar colour ID, optional) -
Chunking / sequential dates - First chunk – supply the intended start date (e.g.,
2026‑05‑31T09:00:00Z). - Subsequent chunks – pass the last date of the previous chunk (via thelastDatefield). The skill will automatically shift the next chunk’s start date forward by one day, guaranteeing a clean “one‑day‑gap” between chunks. -
Run the skill – invoke the
runfunction exported byindex.jswith the event array and optionallastDate.
Implementation Notes
| Feature | Details |
|---|---|
| Google‑Calendar compatibility | Automatically injects the required headers:\x3Cbr>PRODID:-//Google Inc//Google Calendar 70.6//EN \x3Cbr>CALSCALE:GREGORIAN |
| UTC enforcement | All start/end times are normalized to UTC and formatted as YYYYMMDDTHHMMSSZ. Google Calendar accepts this exact format without further conversion. |
| Unique identifiers | Each event receives a UUID‑v4‑derived UID (event-\x3Cuuid>) so calendar clients can correctly sync updates. |
| Color handling | If a colorId is supplied, it’s added as X‑GOOGLE‑CALENDAR‑COLOR:\x3Cid> inside the VEVENT block. |
| Output | Returns a complete .ics string wrapped in BEGIN:VCALENDAR … END:VCALENDAR. Every VEVENT ends with END:VEVENT and the final block ends with END:VCALENDAR. |
| Dependencies | Node ≥ 20 (for crypto.randomUUID()). No external npm packages—pure JavaScript plus Node’s built‑in crypto module. |
| License | MIT – free to copy, modify, and share. |
Why the specific PRODID / CALSCALE?
From community feedback, Google Calendar only imported the generated file when those exact values were present. A generic PRODID caused the “Unable to launch event” error; CALSCALE:GREGORIAN tells Google Calendar which calendar system to assume (Gregorian), which is required for proper time‑zone handling.
