Blossom end rot, it happens when you aren’t watering your plants enough.
I _think_ it’s because underwatering causes tomato plants to start over producing sugars in your fruits, which can cause them to rot. But also a great way to make your tomatoes sweet if you starve them of water a few days before harvesting. Or at least that’s what my dad said to me
Note: if you overwater, they will start splitting from bursting with too much juices
It’s a fine balance

Mine have had this after I went away for a month and trusted my teenager to water them. He did, love him, but not as diligently as I do. Just cut it off and enjoy.
I call it butt rot. Your tomatoes have the butt rot

It’s true that it is caused by calcium deficiency, but that is often caused by irregular watering rather than there not actually being enough calcium around.

Blossom end rot. Caused by lack of calcium uptake. Usually due to inconsistent watering.

Not enough water so cannot absorb the calcium from the soil. The cure , adequate water and could supplement calcium. Indigestion tablets work well if crumbled onto the compost.
