Sorry, I'm afraid not. I usually just keep an eye on which artists are playing in my own neighbourhood (so Belgium, or in very special cases Germany & the Netherlands). We've got a shitload of concerts & festivals in these parts anyway, so sooner or later every artist drops by.
I think I read somewhere that Belgium has the most music festivals in the entire world when you calculate it based on the size of the country & the number of inhabitants. Lucky me I guess
As for Daft Punk, afaik they don't play a lot of shows. At most 10 a year or something like that. When I saw them, it was one of only 3 shows that summer iirc.
