What’s your minimum timeframe?

If someone is vegan for a year then eats meat the next, do we retroactively revoke their year 1 veganism?

If I am vegan for January and then in February eat meat, am I retroactively not a vegan for January?

It sounds like this person is a vegan at least six days a week. I don’t see how Saturday erases Friday any more than 2023 would erase 2022. And I don’t begrudge them becoming vegan again on Sunday. Who would that benefit? Being vegan 6 days a week is way more vegan than most people.
