Index futures settle on the third Friday of every month — so do option expiries. Then there are share unlock dates, earnings disclosure deadlines… can you really keep them all in your head? Trader Days does the math for every key trading date for A-share, index futures, and options traders: a built-in financial event library spanning 5 years, automatic weekend & market-holiday skipping, precise countdowns in remaining trading days, live home-screen widgets and Dynamic Island support, plus multi-tier expiry reminders that roll forward automatically on holidays — so you never miss a single one.
