OmniDate

OmniDate turns every date into a complete time and astronomy dashboard. Instantly compare the same day across multiple calendar systems, including Gregorian, Julian, French Republican, Chinese, Hebrew, Islamic, Persian, Buddhist, Japanese and ISO 8601. Explore: • your position in the year; • sunrise, sunset, solar noon, day length and twilight times; • Moon phases, illumination, distance, moonrise and moonset; • upcoming astronomical events such as seasons, lunar phases, perigees, apogees, supermoons, eclipses and civil-time changes; • historical events linked to the selected date, with categories, details and sources; • astrology and additional calendar information. Customize the dashboard order, choose your preferred calendars, select historical-event categories and define the location used for astronomical calculations. Sharing tools make it easy to send historical or astronomical events to others. OmniDate is designed both for quick reference and for discovering, comparing and understanding the many ways a date can be interpreted. Available on iPhone and iPad, with widgets and Apple Watch support.
