Each year since 1987, I have created a Family Event Calendar listing birthdays, other important family events and holiday/seasonal events. There are currently (2013 Calendar) 110 events. The first Calendar (1987, see January insert above) was created entirely with Microsoft Visual Basic; I now use modern calendar Apps. The self-portrait [Calendar Guru] was made in the early years.
Family Event Calendars are an annual Christmas gift to extended family members.
