Relationship Calendar
Download an .ics file and open it in Apple Calendar, Google Calendar or Outlook. Dates you add again later replace the old copies instead of doubling up.
Copy a link that carries your dates. When your partner opens it, they can add the dates to their own copy. Nothing is uploaded, and anyone with the link can read the dates.
Save a backup file, or bring in a backup or any .ics file.
Removes every date from this browser. Your names and start date stay. Save a backup first if you might want the dates back later.
