Here is a link to a free ephemeris
for 2009. It tells you where all the planets will be.
Okay, I'm looking really quickly, so I might be missing some things, but the 1st and 2nd look good, the 3rd I would skip, definitely skip the 4th (moon square sun all day), I would probably skip the 5th, although earlier in the day on the fifth is better than the evening, and absolutely avoid the morning of the 6th, the evening of the 6th is much better. I would try to avoid the seventh-- moon square venus all day-- but it's not the worst aspect in the world. Moon square venus continues into the morning of the 8th, and then the aspects only get worse, with the moon square to Saturn and Uranus. Yikes! I would avoid that, not only for the sake of the child's natal chart, but because that sounds like a very unpleasant birth experience! Emotionally disturbing, lots of hard work, and just uncomfortable and unsettling and possible negative twists and surprises.
So for the first week in January, your best bets are the 1st and the 2nd.
On the 9th, the negative moon aspects continue until later that evening. So skip the morning and afternoon of the 9th, but evening/late night looks great.
The 10th is a great day, all the way through. The only possible "negative" is that the moon will be opposite the sun from the evening to the morning of the 11th. Some consider this a negative aspect, but I don't necessarily see it that way, just that there's a lot of energy there, that's for sure. A child born at this time would have a very interesting personality. A birth at that time is likely to turn out different than what you expected but probably in a good way, especially since the moon is trine Uranus at that time. Early morning of the 11th, the moon is still opposite the sun but also moves into oppposition with Uranus, and honestly I would avoid that. Then later on the 11th, the moon is still opposite uranus, no longer opposite the sun, but has now moved into opposition with venus. So skip the 11th all day, and also the first half of the 12th. In the evening of the 12th those aspects have cleared up but there is a moon opposition neptune. This is a little bad but not horrible, so I would say the second half of the 12th is a decent time to have a baby. Again, the birth experience itself might not go as you had hoped and dreamed, or might in some way challenge your dreams and wishes. This aspect lasts into the first part of the 13th. The evening of the 13th, the moon is back in opposition with venus again. Remember also that mercury will start retrograding on the 11th, so that is in force for the rest of the month as well.
The 14th-18th I would totally skip-- especially
the 17th and 18th!!! Not good days at all. The morning of the 19th is bad too, but by evening the 19th is fine. The evening of the 19th has a pesky moon square uranus thing, but that's all-- much better than the five days previous. The 20th seems to be a great day. Remember the sun moves into Aquarius early this day, too. Definitely skip the 21st and 22nd. The 23rd is okay. I would skip the 24th through the 26th. The 27th is extremely interesting to me, you will notice if you look at a chart of that day that all of the planets except Saturn and Pluto are located close together in three consecutive signs-- capricorn, aquarius, and pisces. These are three "old" signs, or universal/community signs. This would make for an interesting personality, that's for sure. I wouldn't call it an easy chart, but not at all bad and very interesting. This interesting structure continues into the 28th, of course, but things heat up as Mercury and Mars move into trine with lone Saturn, and Venus forms an oppositon to Saturn. So, the person born on this day would have even more energy to their personality. Venus opposition Saturn is a difficult aspect, but the trines are positive and I still think the whole structure is awfully interesting-- posiibly worth it.
The 29th has both some good and some bad aspects to it. Venus moves into a square with Pluto at this point-- considered a negative aspect-- and this aspect will remain in force for a few weeks. I would definitely skip the 3oth, as the Moon will be square Pluto, and I would NOT want to give birth under that aspect. Yikes. Luckily, the moon will also be sextile to Jupiter at the same time, so hopefully that will bring some comfort to those mamas who do have to give birth at that time. On the 31st, the moon is square to venus and mars, so I would skip that, however on the plus side, the sun and moon are sextile so that's nice.
Whew. Hope that helps. Now, I really just skimmed thios so it's entirely possible I missed important things. So I advise looking into further detail into the days you are interested in, and double check everything I stated here.
