The Calendar page has a private link that Google Calendar, Apple Calendar and Outlook can subscribe to.
Click the feed icon on the Calendar page, turn on Private calendar link, then click Add to Google Calendar or Add to Apple Calendar, or copy the link into Outlook.
The calendar app shows your reminders and the workspace's date property values, from 30 days back to a year ahead. You get a separate link in each workspace.
The calendar app shows the events read only and does not alert you. The notification still comes from Notez.
Google Calendar refreshes subscribed calendars every few hours, so a change can take up to a day to show there.
Turning the link off stops it at once. Turning it on again makes a new one.
Also in this release
The Calendar page is redrawn: thin grid lines, the month in bold, a timed reminder as a dot with its time, and all-day items as tinted bars, each date property in its own color. New reminder is now the + at the top, next to the feed icon.
The "Type @ in a note to add a reminder." tip now stays in the page header instead of appearing only on an empty calendar.
How it all works: Reminders and the calendar.
