Hi Isis, I can certainly share my thinking in recommending the previous time. I'll not be able to scope out the beginning of January (I am not at home and refuse to utilize astro.com for elections. Talk about a headache.) I will upload a chart from astro, but I realize it may go offline at any time, so will do my best to upload a "real" chart later in the day.

Essentially we're trying to locate a good time that occurs within normal business hours. This removes a lot of otherwise good times right from the start. Our focus is twofold: primary importance is getting that Moon/Jupiter conjunction in a good spot and taking advantage of the Moon's trine to the Sun with some great reception. Our second goal is to take the bite out of malefic planets.
The first goal is accomplished in this chart by putting the Moon/Jupiter conjunction on the Descendant. Not only is this the house of the matter, but also represents the bride. We've made the Sun/Moon trine prominent by also placing it in angular houses. The downside of this is, while promising, is likely to let everyone know about your business and make the contents of your marriage kind of public.
The second goal is accomplished by making Saturn the Lord of the First and giving him some responsibility in the matter. Saturn is pretty icky, but we do what we have to do and we put him in a nice cadent house so that he won't be strong, but won't be unfortunate either. We tuck Mars away into the impotent twelfth house, keeping his malevolence out of the way and he aspects neither of the significators.
If the time is before 10:33, Mars takes his place on the Ascendant and that is not good. A time after 11:12 gets the Moon too distant from the Descendant and makes her officially cadent. Other times when the Moon and Jupiter conjunction is on an angle are outside of normal business hours. Though, one thing to consider is that by moving the time forward a few minutes from the time selected for this particular chart will have the Moon take over as hour lord, which will be more conducive to marriage than a Mercury hour. Whether that is something you're going to be able to get and keep the Moon/Jupiter conjunction though I don't know, changing information in astro is too much of a back-and-forth headache.
