Jainism does emphasize fasting as a spiritual practice, particularly during Paryushana, but it does not have a designated month of fasting equivalent to Ramadan. Jain fasting practices are not aligned with the Islamic observance, and the significance of fasting in Jainism does not reflect the same communal and spiritual aspects found in Ramadan.

Buddhism does include periods of fasting, but these are typically not as structured or widely practiced as Ramadan in Islam. Buddhist fasting often varies by tradition and can involve different intentions and methods, making it distinct from the communal and obligatory nature of Ramadan.

Mormonism practices fasting, particularly on the first Sunday of each month, known as Fast Sunday, but it does not observe a month-long fasting period like Ramadan. The practice of fasting in Mormonism is primarily voluntary and not tied to a specific calendar month like Ramadan is for Muslims.

Sikhism encourages moderation and self-discipline in dietary practices, but it does not have a month of fasting like Ramadan. Sikhs celebrate various religious observances that may involve fasting, but these are not comparable in structure or significance to the Islamic month of Ramadan.
