The number 3 is your current challenge number, your current life cycle number, and the number of the first letter of your name.

The challenge number 3 ends next year, after which the 3 (creativity and social interaction) will attract its own challenges.

The life cycle number 3 ends in 2020, at which point the life cycle becomes the number 6.

The first letter of your name is static. It won't change unless you change your name.

The second part of the 3:49 you are seeing, the number 49, reduces to the number 4 (4+9=13, 1+3=4).

I do not see any corresponding and applicable numbers in your profile.

The number 4 has to do with building for the future paying and paying attention to details. The number 49 slants that toward building for mankind.
