@evacide Wow.
Women, time to go back to paper calendars.

@evacide @CStamp that’s a fair assumption but it does segue nicely into a little story about the oldest calendar found by archaeologists which is basically 28 notches in a bit of wood. Historians (mostly men) assumed it was associated with some sort of moon worship however there is another reason why some primitive humans may have wanted to track a 28 day cycle @Sim0n @evacide "a new study found only 13 percent of women have a 28-day cycle" and many don't even have regular X number of days. https://www.healthline.com/health-news/forget-28-day-cycle-womens-fertility-is-complicated Male historians have been making a lot of assumptions based on their lack of understanding and pre-concieved biases, such as now we are learning that those women who were buried with hunting gear actually were hunters. @Sim0n @evacide @CStamp@mastodon.social That's using a stick, not the moon. Also, stick to subjects you know something about. @bergamlaimerin @nyx @Sim0n @evacide Hormone-based contraceptives generally make periods predictable, which is one of many reasons some women like to used them. |
@CStamp @evacide I think this is one of those cases where it's fundamental to use stuff that is open and that stores data strictly on your device. We use Periodical (https://arnowelzel.de/en/projects/periodical), which is a bit barebones but does the job; Drip (https://bloodyhealth.gitlab.io/) also is open and all-local and seems to be the much more refined, but we never tried it.
