@Loewian Do we really need a tag for shushan-purim?

@IsaacMoses Why not? There seem to be many questions about the topic... Is there a minimum number of questions per topic or other meta rule for determining if a topic merits a tag?

@Loewian there are many questions that start with the letter T but we don't need a tag for that. The onus is on the one making a new niche tag to explain how it helps the site and isn't just clutter.

I don't see how this tag isn't just clutter. We don't have tags for second day Rosh Hashanah in addition to first day Rosh Hashanah. Pretty much any relevant question here can already be found with the Purim tag and the word shushan or 15, as you demonstrated quite effectively by quickly finding all relevant questions to add the tag to.

Nor first days of Pesach vs last days of Pesach.

Each day of Chanukkah

Etc.

@DoubleAA not all. I added it to one he hadn't found.

Someone interested in the topic of SP will be aided by the tag's existence.

@msh210 that's trivially true of any tag name

@msh210 pretty much all were indeed found
