About

Anniversaries is a Home Assistant integration that counts down the days to a recurring date such as a birthday. Each entry becomes a sensor whose state is the days remaining, or the days since the last occurrence when count up is chosen. Attributes include the next date, weeks remaining, and years passed, and the year can be left out if unknown. An optional half anniversary date can also be shown. Entries also appear in the Home Assistant calendar, which shows the next configured anniversary. Settings cover one-time events, custom icons for today and for soon, and the number of days counted as soon. It works locally and is set up in the UI.

From the README

The 'anniversaries' component is a Home Assistant custom sensor which counts down to a recurring date such as birthdays, but can be used for any anniversary which occurs annually on the same date.
Any anniversaries entries configured will be added to the home assistant calendar. This also generates the calendar.anniversaries entity, which shows information about the next configured anniversary. N.B. At the moment, only the next occurence of the anniversaries are added to the calendar
