Big Day turns the dates you're excited about into bright, glanceable countdowns you can pin anywhere β your Home Screen, Lock Screen, and StandBy. Holidays, birthdays, trips, paydays, due dates, anniversaries β add a countdown, give it a colour and an icon, and watch the days tick down (or up) every time you glance at your phone. WHY BIG DAY β’ Start free β create your first countdown and pin it as a widget, no account needed. β’ Beautiful, brightly-coloured cards that look great on any screen. β’ The little details other countdown apps get wrong: it says "Today" at zero, handles "1 day" correctly, and uses your local time zone β never UTC.
