How to add
- Google Calendar: press the button, sign in to Google if asked, then confirm adding the calendar. On a phone, do this in the browser.
- Apple Calendar: on iPhone, iPad or Mac, press the button to open Calendar, then choose Subscribe.
- Other calendar apps: copy the link of the Apple Calendar button (it starts with webcal://) and paste it where the app subscribes to a calendar by URL. A downloaded .ics file is a snapshot and does not update.
- Events are all-day and marked free, so they do not block appointments. To remove them, delete the subscribed calendar in your calendar app.
How it is computed
Lunar dates, leap months and solar terms are computed for Vietnam time (UTC+7); calendars computed for another time zone can differ by a day. Solar terms are placed on the day the term begins. See Method and accuracy.
