Talk:J2000.0

ICRS vs J2000
The article is a bit confusing about ICRS vs J2000.0. From what I understand (I'm a bit confused myself), J2000.0 is simply an epoch, with an associated Earth meridian and equator. ICRS may roughly agree with these coordinates, but is defined completely independently from them. I'm thus not sure that International Celestial Reference System should redirect here. It'd be great if an astronomer could clarify this. MFago 16:18, 24 March 2006 (UTC)

Julian Calendar
I'm reverting the deletion of Category:Julian Calendar. As J2000 is essentially a specific Julian date I think the category is relevant. MFago 03:17, 13 April 2006 (UTC)
