The calendar method is the simplest but has the highest failure rate because it relies solely on predicting when ovulation will occur based on the length of the menstrual cycle, which can vary from month to month. This method is not recommended for women with irregular periods. The other methods mentioned (basal body temperature, cervical mucus/ovulation, and sympto-thermal) require more daily monitoring and observation but have a higher efficacy rate.
