Two options: You can either translate the Day and Night textures by the
opposite amount:

texture {
gradient x
scale EarthScale*2
texture_map {
[0.4 Day translate<EarthScale,0,0>]
[0.6 Night translate<EarthScale,0,0>]
}
translate <-EarthScale,0,0>
}

Or you can use pigment_pattern to translate the *pattern* without affecting
the texture itself:

texture {
pigment_pattern {
    gradient x
    scale EarthScale*2
    translate <-EarthScale,0,0>
}
texture_map {
[0.4 Day]
[0.6 Night]
}
}
