I was questioning my American brother in law – who spent this weekend overindulging and regretting between the moments of gratitude – why the US holiday happens on a Thursday. Little did I realise that it was actually the decision of Honest Abe back in 1863. I had never seen the full text of the Thanksgiving Proclamation before. For all of you in the States who are in need of some distraction from the dinner table, it’s worth a read!
It has seemed to me fit and proper that they should be solemnly, reverently, and gratefully acknowledged, as with one heart and one voice, by the whole American people. I do therefore invite my fellow-citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next as a day of thanksgiving and praise to our beneficent Father who dwelleth in the heavens.
