Here is a sample greeting that is laced with a maxim about the value of days as gifts. It is easy to find gifts that rank higher than any day of the week. From a Christian perspective there is eternal life, way more valuable than any day. How does one receive the best gift EVERY DAY. Does each day get better than the last? They all cannot be the best.

A day is precious but is gone in 24 hours.
Not only are greeting mills products likely to be disguised hacks, scams, and phishing tactics they also spread meaningless tripe like “the greatest gift is waking up”, The greatest gift cannot happen every day.
