Hi dontplaceliterature. That is interesting. It's been some 35 years since my last circuit assembly so I've forgotten things like that.
I did a little search on my own WT Lib CD and you may be surprised at what I found.
As his knowledge of Scriptural truth increased, so did his understanding of birthday celebrations and worldly holidays and Jehovah’s view of them. When this man’s wife organized a social gathering for Father’s Day, he politely refused to attend. She felt, though, that he did not love her anymore and was putting his religion ahead of her and the family. He kindly explained that applying what he was learning from the Bible was helping to transform him into a better husband and father.The Watchtower, 1994, 3/15 p. 8, Jehovah’s Witnesses Around the World--The Bahamas.
True Christians do not need "Mother’s Day," "Father’s Day," "Christmas Day," "Easter Day" or other holidays that are outlined by the world because, while it is true that some persons might in all sincerity give on these occasions out of love, when they become Christians they refrain from having their giving marred by association with any holidays of pagan origin.The Watchtower, 1968 2/15 p. 119 par. 12, Working What Is Good Toward Those in the Faith.
As a footnote, one of my sons -- not a JW -- had me over to his place yesterday for Father's Day and treated me like a king. Great meal which this 49 year old prepared, my choice of movie on his 47" LED flat screen, and best of all -- some bonding that we'd never had as he only recently moved nearby.
