Scheduling from the command line saves time when you're already in the terminal. Here's how nylas calendar events update works.

The nylas calendar events update command modifies an existing event on your connected calendar. Pass --id for the event to update, then any combination of --title, --start, --end, or --location to change.

Quick Start

brew install nylas/nylas-cli/nylas
nylas init
nylas calendar events update

Examples

Change meeting time:

nylas calendar events update --id abc123def456 --start 2026-03-30T14:00:00Z --end 2026-03-30T15:00:00Z

Add a participant to an existing event:

nylas calendar events update --id abc123def456 --participants alice@example.com,bob@example.com,charlie@example.com

How It Works

Calendar APIs are notoriously inconsistent across providers. Google Calendar uses RFC 5545 recurrence rules, Outlook uses its own format, and Exchange has yet another. The Nylas CLI normalizes all of this behind a consistent interface.

Syntax

nylas calendar events update --id EVENT_ID [--title TITLE] [--start START] [--end END] [--location LOC]
