A new, upgraded version of an Internet online Mikvah Calendar has just been released, allowing Jewish women around the world to know exactly when and how to perform the Torah commandment of Family Purity.

The Online Mikvah Calendar provides all the complex calculations that go into determining the exact times for immersion, easily and with simple, clear instructions.
The rabbinically-approved guide offers information according to Ashkenazi, Sephardic and Chabad-Lubavitch customs, with times and dates automatically adjusted to the user's exact location. In addition, the site offers reminders to the user through SMS texting by cell phone and via email.
The site was produced in memory of Rebetzin Rivkah Holtzberg and her husband Rabbi Gavriel Holtzberg and “the Mumbai Kedoshim” – the two Chabad-Lubavitch emissaries and their guests who were murdered by Islamist terrorists in November 2009. It provides information in English, Hebrew, Spanish and French.
“As you enter, we hope that you will begin to experience the tranquility and holiness that characterize performance of this Mitzvah,” a message welcomes the user on the home page. “We are privileged to be by your side as you anticipate the spiritual rejuvenation and intimacy that each new cycle brings.”
