No, the calendar journal is completely undated and customizable. You’ll be able to use it for a whole year from when you first being using it. So if you begin use in August 2020, you’ll be able to use it till August 2021.

Getting your cycle back after birth control will be different for everyone- some get their cycles back within a month after stopping hormonal contraceptives while it can take several months for others. So it's really up to you. I would, at the very least, write down on the journal the last day/date you stopped taking the pill, or got your IUD removed, etc.

Once you begin feeling any type of changes within your body, or see changes in your cervical fluid / mucus, breast tenderness, changing emotions and energy levels, etc., start tracking because all of these changes will happen prior to your first authentic menstrual bleed. Ovulation always precedes bleeding, and there are fertility signs associated with that which you would want to keep track of. In the mean time, you can dive into resources like the Fertility Friday Podcast which is all about cycle tracking and fertility awareness and you can read books like Garden of Fertility or any of the other books I have on the recommended reading list

This resource does not have any religious component or goddess worship.

This resource is very customizable, but was made in hopes that women would become more in tune with their cycle and how that corresponds to the natural cycles of the earth. And, so that women could chart their fertility cycles and become less dependent on pharmaceuticals or technology to manage their fertility.

The calendar really does not address sex, other than to explain that only for a distinct period of time during a cycle is one fertile which is observable due to peak amounts of estrogen leading to a certain type of cervical fluid. The user of the calendar decides (after educating themselves further), what to do with that information if they are charting their fertility in order to make family planning decisions. Otherwise, having body literacy is useful for health reasons, to gain greater respect and understanding for your own body, and greater autonomy over it for the rest of one's life.

There are a couple other small references to sex, but only from a scientific perspective, not to encourage or discourage sexual activity.

I often think that if young girls were introduced to this information earlier, they would make healthier sexual decisions for the rest of their lives! I sure wish I had had this information starting at age 12 to be honest :)

There is a page per month to write down your new moon wishes and a 2021 / 2022 lunar calendar insert in the back pocket of the journal. I think it's nice to observe your feminine cycle alongside the lunar cycle and how the two cycles both have energetic ebb and flows. I put my lunar poster up on the fridge as an easy place to see everyday. However, this resource is mostly to chart the menstrual cycle. If you're looking for more of a lunar type journal, check out The Moon is My Calendar by April McMurtry or Lunar Abundance Reflective Journal by Dr. Ezzie Spencer

Many moms purchase this calendar for their daughters when they first begin menstruating as it's already a vulnerable confusing time for young girls. Having a menstrual calendar makes it seem more fun, something to celebrate and less taboo.

The calendar is customizable to the user, so it's really geared towards whatever the user wants to make of it.

For older users, its a great way to track their fertility signs for conception / contraception purposes, while others just like getting to know their bodies better and how the changing hormones can affect their mood / energy, breast tenderness, etc.

Either way, its a great way to introduce honoring and learning about your body as a young pre-teen. There is one reference to sex in the journal that I can think of, but it has to do with the science behind how the cervix changes throughout the month.
