Vietnamese lunisolar calendar for checking whether you should be a vegetarian today or not.
Some lay-followers of Buddhism are intermittent vegeterians. This means that they avoid eating meat on certain days during the year. Vietnamese buddhists typically use the Vietnamese lunar calendar to determine their vegetarian days. However, their civic calendar is usually a solar one. As such, it can be difficult to keep track of their vegetarian days.
This web app was created with Vietnamese buddhists in mind. As such, the Vietnamese calendar is used instead of the Chinese calendar or any other variants.
