Zikaron is a thoughtful tool designed to help individuals, families, rabbis, and communities navigate the Jewish mourning process with clarity and ease. The app’s core feature is a powerful calculator that determines the key milestones of the mourning period according to the Jewish calendar, including shiva, shloshim, and upcoming yahrzeit dates, while properly accounting for interruptions from Jewish holidays. By entering the date and time of passing and burial, the calculator automatically generates the full mourning timeline. The app provides both Hebrew and Gregorian dates so users can easily track each stage of mourning and observe traditional practices with confidence. Zikaron simplifies what can otherwise be a complicated process of determining dates across multiple calendar systems. The app automatically adjusts for Jewish holidays that interrupt mourning practices, ensuring that the calculated dates follow traditional Jewish law and custom. Beyond the calculator, the app includes additional resources to support mourners throughout the mourning period. The Kaddish Tracker helps users follow the traditional period for reciting Mourner’s Kaddish. Users can track their progress and optionally enable reminders to help maintain the daily practice of honoring a loved one’s memory. The Mourning Guide provides clear explanations of Jewish mourning customs and condolence practices. The guide helps users understand the traditions associated with shiva, shloshim, and the first year of mourning, making it easier for mourners, family members, and community members to participate in these practices with understanding and respect. The Memorial Prayer Library includes a collection of traditional Jewish prayers and texts used during mourning and remembrance. Each prayer is presented with Hebrew, transliteration, and English translation so that users of different backgrounds and levels of Hebrew familiarity can access the liturgy. Together, these features create a single place where mourners can find the dates, prayers, and guidance needed during a difficult time. Features include: • Shiva, Shloshim, and Yahrzeit calculator based on the Jewish calendar • Automatic adjustment for Jewish holiday interruptions • Hebrew and Gregorian dates for mourning milestones • Automatic generation of the first ten Yahrzeit dates • Kaddish tracking with optional reminders • Mourning guide explaining Jewish mourning rituals and condolence practices • Memorial prayer library with Hebrew, transliteration, and English translation Zikaron was created to make it easier to observe tradition, remember loved ones, and navigate the mourning process with dignity, clarity, and care.
