Most Destiny players want to know when Xûr is at the tower next weekend, well, there is a website out there that will track his time of arrival and how long until he's at the tower. Link: http://isxuratthetower.com/ There's barely anything on there (It's not in development, it's finished) but, it will say how many day's and hour's left until he is there. I hope this post is helpful for different timezones as well.
