Store description excerpt
Every month has days you only miss because nobody reminded you. Friday arrives and you had not noticed it was SQ week. You remember the last day with rights one day off, and the dividend is gone. You learn a BOJ decision is out on the day it lands. Koyomi keeps just those dates within reach. ■ No prices, no news It shows dates, and what each date means. No charts, no quotes, no tickers. It makes no network requests, so it opens in airplane mode and underground. ■ What is in it · SQ and major SQ, and the last trading day before each · The last day with rights, the ex-rights day, the record date (settlement is T+2) · Bank of Japan policy meetings and the Tankan survey · FOMC, US employment data, US market holidays and early closes · Exchange holidays, and the first and last sessions of the year · The NISA year-end buying deadline and the tax filing window · Scheduled Nikkei 225 constituent changes Holidays and closures are included from 2020 through 2040, with substitute holidays and citizens' holidays worked out. ■ The rules, applied correctly SQ is the second Friday, but when that day is a market holiday it moves EARLIER, to the previous session — not later. The last day with rights follows the T+2 settlement that took effect in July 2019. You do not have to count any of it yourself. ■ Reminders (Koyomi Pro) A week before, the day before, or on the day — chosen per category. Notification times are Tokyo time. Lock Screen and Home Screen widgets show what is next. ■ Free · See dates and event names on the calendar · The next 7 days as a list · 日本語 / English / 简体中文 · Light and dark, in two palettes ■ Koyomi Pro (one purchase) · Reminders a week before, the day before, or on the day · Lock Screen and Home Screen widgets · What each date means, the dates related to it, and the source · The schedule beyond 7 days · Filter which categories appear · Future updates included There is a 7-day trial. No card, and it is not an Apple subscription. Nothing is charged when it ends — reminders and widgets simply stop, and the calendar stays free. ■ What it does not collect No account. No network, so nothing to send. No ads, no analytics. — Dates follow publications by public bodies and the exchange. This app provides schedule information only and does not solicit or advise on investments. Dates are subject to change; check the official announcement before acting on anything that matters. ■ Links Website https://koyomi.glspace.co.jp/en/ Support https://koyomi.glspace.co.jp/support.html#en Privacy Policy https://koyomi.glspace.co.jp/privacy.html#en Terms of Use https://koyomi.glspace.co.jp/terms.html#en
