Stock Market Hours & Trading Calendar Widget

A simple widget/app that shows when global stock markets open/close, displays market holidays, and sends notifications before market opens. Solves the problem of traders and investors constantly searching 'what time does the stock market open' by providing instant, always-visible information.

Retail trading participation surged post-2020 and has stayed elevated, with millions of new investors now tracking multiple global markets across time zones — a genuine behavioral shift that creates sustained demand for this kind of utility. The problem is that well-maintained free resources already exist: Marketwatch, Investing.com, and even Google's direct answer to "what time does NYSE open" handle the core query instantly, which is the sharpest threat to any paid version of this. At $500–2k/month the revenue ceiling is low but plausible if distribution runs through a WordPress plugin, Notion widget, or broker affiliate angle where utility converts to passive income without ongoing support load. The single most likely failure mode is that the addressable paying audience is essentially zero — people who need this information are already getting it free from five different places, and there's no clear wedge to charge for something this commoditized.
