You all are so mistaken.
What does celebrating wedding anniversaries and having baby showers have to do with celebrating birthdays? Wedding anniversaries are to celebrate an accomplishment as what celebrations are for. Celebrating the anniversary of one's birth is not an accomplishment. Especially for children.
It is just an excuse to have a party. And a foolish excuse when people spend hundreds of dollars on it.
"The ‘gentle times’ was a period of 42 months during which the ‘holy city’ was ‘trampled’"
No, that is not the gentile times. You didn't consider that Nathan told David that his offspring would sit on Jehovah's throne forever. But that ended when Jehoiakim lost that sovereignty. To not have that prophesy fail, Jehovah paused that for 2520 years. The Gentile times is from when it was paused until it stopped and Jesus became king because he didn't become king when he was on earth. It's that simple.
