All transits simply act as background influences until they make a mathematical aspect to another planet or angle ie: Ascendant and Midheaven.

learn how to read an ephemeris, the glyphs are the shorthand for signs/planets
Now Neptune dissolves things, causes confusion, illusions and rose tinted glasses especially if in hard aspect to Angles or planets. It can be a spiritual, artistic awakening, but there are not many people who can advance or benefit their lives (unless there is natal potential of course) with Neptune. But having said this if you are ‘supposed’ to be Learning a Lesson in this life and Neptune draws a veil across your mind so you don’t see things clearly enough to be objective—– then this pawn in chess has done it’s job….
Neptune Transits the Fourth House “This cycle may bring some confusion about your connections to your past, family, or home life. You are more idealistic than usual when it comes to relationships with close loved ones, particularly family, which can cause a few problems if you�re not careful. A noncommittal attitude in your personal life could leave people in your life feeling frustrated with you as you attempt to find yourself. Alternatively, there could be some distancing involved with family members, or family members need special care requiring you to make some sacrifices. During this cycle, you may find that you require more sleep than usual and that you are easily drained.” http://www.cafeastrology.com/neptunetransitshouses.html
I notice you have a neptune singleton like myself and you can read how mine functions here
I use—– 1° approaching, 1° exact and 1° departing. If you click on the link listed below for the online ephemeris it will list all planets at any given time. Learning astrology is like learning a new ‘language’ and obviously the more effort you put linto something the more your knowledge and understanding will increase. All transits act as ‘background’ influences through a house, until it makes a mathematical aspect to a planet inside or an Angle. Slight problem I have with astro.com is they use 10’app 10’ exact and 10’ departing. I tend to reduce the orb ratio down (found in Extended Chart selection) to 85% to bring them in line with mainstream views..
For ‘timings’ I would look to the retrograde hit as the most important trigger, then look to see what the quicker planets are doing especially mars & mercury —
astro.com has fee six month transit forecast plus when you get into Extended chart selection, look at the three tabs after calculating a chart under ‘method’ default is circular wheels (on left), middle is special charts and in their you get graphic ephemeris 1yr (or 5years) with natal = transits for 1yr and lots more.
The danger of this influence is that it is likely to kick your props out from under you. In your job or any other activity that is important to you, something may happen that will make it very difficult to continue in your present direction. This event is probably not something that can easily be foreseen, and it will be difficult to describe even as it is happening. It can take the form of a psychological crisis that results in your feeling that you cannot go on. You may feel suddenly weak and ineffectual, even though others may not be able to see any reason for this. It is also possible that events in your most personal life will make it difficult to continue in your profession with the self-confidence and assurance that you need to be at your best. There may be domestic problems or difficulties with members of your immediate family. Someone very close to you may be doing or saying things to you that are very discouraging.
But this influence can also have another effect. You may no longer feel like advancing in your external social roles now, because you feel they have become meaningless and empty. You may want to withdraw a bit and look at your life in terms of your own criteria instead of others' and ask whether you are accomplishing what you yourself want to, rather than what others want. Sometimes in life we go ahead too fast and lose track of our original purposes. This is an excellent time to sit back and look at whether this has happened to you.
Many important elements of your life may come to an end and pass out of existence now. Let them go, for it is the right time for this to happen, and it will ultimately be good. This is a time to renounce those things, for you will soon discover that you do not really need them anyway. As the old saying goes, we are naked when we come into this world and when we leave it. Therefore what we have inside is important. Now is the time for you to find the strength of what you have inside.
