Excuse me but if it is 149 million light years away, what time span are they looking at on that planet or put another way what date would it be on that planet?

149 light years, not 149 million

Hmm.. Well, as someone else mentioned this planet is merely 149 light years away, not 149 million light years, which would put it way, way outside the boundaries of the Milky Way Galaxy altogether (the distance across the Milky Way is about 100,000 light years).

However, to answer your question, regardless of how far away a planet is, the current date on that planet would be the same as the date on earth. However, the light reaching our planet from that planet will have travelled about as long as the distance in light years.

So, we are seeing light that left this planet's solar system about 149 years ago - in 1856.

PS. And if the planet were 149 million light years away, from here we would be seeing it as it was 149 million years ago. The date on the planet itself - assuming it was still there - would be equivalent to the date on earth.
