Founder and co-creator Rivkah Bloom, who holds a masters degree in computer science from MIT, says she was inspired by women approaching her for help with the mathematics of the laws of purity.

"Women needed help with family purity calculations. But women today are internet and computer savvy. They asked me to develop a program to help them do it on their own," said Bloom.

Working with a colleague from MIT, the Mikvah Calendar program took Bloom four years to develop. Launching its English site in 2009, the website took off fast. Hundreds of thousands of women from around the world visited the site in its first few months of business. Strong requests from users propelled the team to translate the site into Hebrew.
