Statistical publication calendar
The .ics files follow the iCalendar standard and can be integrated with most popular calendar applications (Google Calendar, Outlook, Yahoo, Mozilla Thunderbird, Zimbra, Apple ICal, etc.)
It is recommended to link your agenda with the calendar or calendars that you want to view because, in the event of any modification to the scheduled dates, the corresponding calendar will be automatically updated.
Below are shown, using the Google Calendar viewer, the expected dates of AEAT statistical publications.
