Use Daynode your way.

Google accounts

In Settings → Accounts, add your work and personal Google accounts. Use the calendar picker beside All calendars to show or hide calendars from each account. Calendar data stays in a local database, and sign-in tokens stay in macOS Keychain.

Reconnect or remove each account separately. Removing an account only removes it from this Mac; Google events stay unchanged, and unsent edits are kept under Recovered events.

Calendars and events

In Settings → Calendars, choose your default calendar or use Rename to give a Google calendar a name in Daynode. The original name stays visible below it. Custom names are saved on this Mac and do not change Google Calendar. Clear a custom name to restore the original.

When creating an event, use Invite people and Add location beside Attach. Choose 24-hour or 12-hour time in Settings → Defaults.

Command line

Install one package to read and change the same local items as the desktop app.
