Masks come on when the flu starts to circulate, which differs from year to year. I do not recall when exactly they were appearing in grater numbers in 2019. Once seasonal allergies hit, then you see even more mask usage. Depending on the year and what one is allergic to, Some wear masks from early Fall until Golden Week, the first week of May. I used to wear a mask against hay fever here. While allergies trouble me once it turns too cold to keep the windows open, those are dust and dust mite allergies. From late December some years but hopefully only from late February to May is when my hay fever allergies kick in. There are those who wear masks year round.
