Tim, I think Sundays are always welcome and happier than other days. If you are particular about this only Sunday, then it may mean some special significance to mention it.
For me, it is a good one as I have published one of my draft hubs on Saturday and started working on the second draft today.
These two were started 3 weeks back as I wanted to publish these two by 31st March to reach at least the 45 hubs target set by me. this time within 3 year period.
My targets have been got decreased as the years rolled on. The first year, I set a target of 24 hubs and done only 18 hubs. The second year, I set 18 hub target and completed only 15. The third year, I didn't set target and published 11 till now. So, one more will make it total 45 published hubs to my credit. Is it worthy?
