I have a list of sites I visit, some daily, some weekly, and some monthly, and I don't want to forget to visit them (they give away free stuff). In order to ensure I do remember to visit them, I use a Notezilla note to automatically open them on a specific time & date, and it repeats daily, weekly, or monthly, as required. Since I always have Notezilla open any way, it doesn't use any extra resources that it wouldn't normally have already used.
If you have Notezilla or another sticky note app, or task scheduler, or anything else capable of opening a URL and scheduling it, that you normally use any way, that could be a good solution for you.
