The History of Menstrual Calendars and Why They’re Still Relevant Today
Menstruation, or the monthly shedding of the uterine lining, has been a natural process in women’s bodies since the beginning of humanity. However, for centuries, it was shrouded in secrecy and stigma, with little information and resources available for women to track and manage their menstrual cycles. This led to the creation of menstrual calendars, which have evolved over time to become important tools for women’s health and empowerment. In this blog post, we will take a journey through the history of menstrual calendars and explore why they are still relevant today.
Ancient Civilizations and the Origins of Menstrual Calendars
The earliest documented use of menstrual calendars can be traced back to ancient civilizations such as the Egyptians, Greeks, and Romans. These calendars were primarily used for religious and spiritual purposes, as menstruation was often seen as a sacred and powerful process. In ancient Egypt, menstrual blood was believed to have healing powers and was used in various medicinal rituals. The Greeks and Romans also had goddesses associated with menstruation, such as Hecate and Juno Lucina.
The use of menstrual calendars in these civilizations was also tied to the lunar cycle, as it was believed that women’s menstrual cycles were connected to the phases of the moon. This further emphasized the sacred and mystical nature of menstruation.
Medieval and Renaissance Periods: The Rise of Medical Knowledge and Superstitions
During the medieval and Renaissance periods, there was a shift in the understanding of menstruation. Medical knowledge about the female reproductive system began to emerge, but it was often mixed with superstitions and false beliefs. Women were viewed as inferior and impure during this time, and menstruation was seen as a curse or punishment for Eve’s sin in the Garden of Eden.
Despite these negative attitudes, some women still used menstrual calendars to track their cycles. However, these calendars were not widely available and were often kept secret due to the shame and taboo surrounding menstruation.
The 19th Century: A Turning Point for Menstrual Calendars
The 19th century saw significant advancements in women’s health and rights, including the rise of the feminist movement. This led to a renewed interest in menstrual calendars as a tool for women to understand and take control of their bodies. In 1873, physician Dr. Alice Bunker Stockham published “Tokology: A Book for Every Woman,” which included a menstrual calendar for women to track their cycles. This was one of the first mainstream publications to openly discuss menstruation and provide a resource for women to manage their periods.

In the late 1800s, the first commercially produced menstrual calendars were introduced, such as the “Ladies’ Calendar” by Kotex. These calendars were often marketed as a way to help women plan their daily activities around their periods, as well as to promote hygiene and prevent unwanted pregnancies.
20th Century: The Evolution of Menstrual Calendars
The 20th century saw significant advancements in women’s health and rights, leading to a boom in the production and availability of menstrual calendars. In 1921, Margaret Sanger opened the first birth control clinic in the United States, and in 1931, the first disposable menstrual pad was introduced by Johnson & Johnson.
During this time, menstrual calendars also became more scientific and accurate, with the introduction of the Basal Body Temperature (BBT) method and the use of ovulation predictor kits. These tools helped women track their fertile days and plan for pregnancy or contraception.
The Digital Age and the Continued Relevance of Menstrual Calendars
With the rise of technology, menstrual calendars have also evolved. Today, there are numerous smartphone apps and websites that offer menstrual tracking and management tools. These digital calendars not only track menstrual cycles but also allow users to log symptoms, mood changes, and other health-related information. Some apps even use artificial intelligence to predict future cycles and offer personalized tips and advice for managing PMS symptoms.
Despite the advancements in technology, traditional paper calendars are still in use by many women. Some find it more convenient and discreet, while others enjoy the creative aspect of tracking their cycles using stickers or drawings.
Why Menstrual Calendars are Still Relevant Today
In a world where women’s health is often stigmatized and neglected, menstrual calendars play a crucial role in empowering women to understand and take control of their bodies. They can help women identify irregularities in their cycles, plan for pregnancy or contraception, and track symptoms related to PMS or other menstrual disorders. Moreover, they can also be used to break the stigma and shame surrounding menstruation by normalizing the conversation and educating women about their bodies.
In conclusion, the history of menstrual calendars is a reflection of the progress and challenges in women’s health and rights. From their ancient origins to the modern digital age, these calendars have evolved into important tools for women’s health and empowerment. They continue to play a relevant role in society and serve as a reminder of the power and strength of women’s bodies.
