which president of the united states first observed father's day as an annual event?
By the end of the war, Fatherâs Day may not have been a federal holiday, but it was a national institution. In 1972, in the middle of a hard-fought presidential re-election campaign, Richard Nixon signed a proclamation making Fatherâs Day a federal holiday at last. Today, economists estimate that Americans spend more than $1 billion each year on Fatherâs Day gifts.
