Sun Conjunct Retrograde Mercury...

starts on April 9 (using a 1 degree orb), is exact on April 10 at 5.36am in Kilmore, leaves on April 10.  Both at 19 degrees and 36 minutes of Aries.

Whatever the Sun touches tends to come into prominence in our lives,and the conjunction is a powerful connection that suggests the end of something old, and the beginning of something new.

Mercury represents our thinking, attitude and ability to communicate in general with the world around us, and also to connect with it.  Personally, it represents the people and situations as shown by which houses are ruled by it (house cusps with Gemini or Virgo on them).  Since Mercury is currently retrograde, it seems that the themes represented by it will have gone back to a previous state, or you will need to review them.

Also look at the house that the conjunction is falling in, and the one with Aries on the cusp in order to get a feel for where a new start is needed.
