In this file photo from April 1977, San Francisco Supervisor Harvey Milk, left, and Mayor George Moscone are shown in the mayor's office during the signing of the city's gay rights bill.
If we are all alive on Sunday, Californians will awaken to celebrate the first official state day of recognition for an openly lesbian, gay, bisexual or transgender person.
Last year Gov. Arnold Schwarzenegger signed into law the Harvey Milk Day bill, in honor of the slain San Francisco supervisor who fought for LGBT rights.
Friday current California Gov. Jerry Brown issued a proclamation declaring Sunday as "Harvey Milk Day" in the state.
"Harvey’s life was cut short far too soon, but his legacy of hope, tolerance, and equality lives on," the proclamation reads.
Milk was killed along with San Francisco Mayor George Moscone in 1978 when Supervisor Dan White shot them at city hall.
The openly gay politician would have turned 81 Sunday.
In the 1970s, Milk famously took calls at his social and political campaign headquarters in San Francisco from gay, lesbian, bisexual and transgender youth seeking hope about the future.
Sunday, the site of that one-time base, the Castro Camera store, will open as a suicide crisis call center for The Trevor Project, a nonprofit that provides crisis intervention to LGBTQ youth.
The unveiling of the Trevor Lifeline's Harvey Milk Call Center at 575 Castro St. is scheduled for 11 a.m.
The ribbon untying ceremony and tours, which are free and open to the public, will be attended by political and gay rights luminaries, according to The Trevor Project.
House Minority Leader Nancy Pelosi and Sens. Barbara Boxer and Dianne Feinstein have said they will try to attend, a project spokeswoman said.
Also in attendance will be members of Milk's inner circle, including Cleve Jones, Anne Kronenberg, Frank Robinson, Michael Wong and Dan Nicoletta.
Stuart Milk, Harvey Milk's nephew and co-founder of the Harvey Milk Foundation, will also be there, along with Academy Award winners Dustin Lance Black and James Lecesne, a co-founder of The Trevor Project.
State Sen. Mark Leno and Board of Supervisors President David Chiu will be among the local politicians attending the opening.
Lecesne co-founded The Trevor Project after helping create an Oscar-winning short film about a 13-year-old boy who tried to commit suicide when his friends rejected him because of his sexuality.
