Time is the first filter
A guild whose raid nights you cannot make is not a fit, however good the rest looks. That sounds obvious, and yet the most common reason people leave a guild within two months is a schedule that never quite worked. Treat your available evenings as the first filter, before class, faction or atmosphere.
Be honest about what “available” means. An evening you can make if nothing else comes up is not an available evening. Count the nights you can commit to almost every week, and start there.
Set your availability on your profile
Your profile has an availability strip, the days of the week you can usually play, plus a free-text line for hours such as “weeknights after 8 pm Central”. Fill in both. The days feed the match score on every guild page; the hours help recruiters judge whether a 7 pm Eastern start actually works for you.
Set your timezone too. It is used to convert guild schedules into your own time on the guild page, so you never have to do the arithmetic yourself.
Read the raid-day strip
Every guild card shows a strip of seven letters, Monday to Sunday, with the guild’s scheduled days highlighted. The guild page then shows the full weekly grid with start and end times in the guild’s timezone and, when your browser allows it, the same slot in your time.
Look at the end time as carefully as the start. A raid that begins at 7 pm and ends at 11 pm Eastern is a 4 pm to 8 pm commitment on the West Coast, which may collide with dinner, commutes or family time. The site shows both ends; make sure you look at both.
Use the schedule filters
The guild directory lets you filter by raid day. Tick the days you can make and the list shrinks to guilds that raid on at least one of them. Combine it with your faction and role to get a short list worth reading properly.
On each guild page, the fit box breaks the match down by factor. The schedule line tells you how many of the guild’s raid nights fall inside your availability. Two out of two is ideal. One out of three usually means you would be a part-time raider, and you should ask the guild how they feel about that before applying.
Ask about the nights that are not on the page
A schedule shows the fixed commitments, not the whole week. Ask whether there are optional nights, such as an alt raid or a dungeon evening, and whether “optional” is truly optional. Ask about daylight saving changes: most North American zones shift together, but a guild with members in Arizona or overseas may have a slot that moves for some people twice a year.
If a guild runs an open night, go. An hour in their voice channel on a real raid night tells you more about the pace of the evening than any amount of text.
When nothing fits
If your available nights do not match any guild that is recruiting, you have a few options. Relaxed guilds often raid on fewer, more flexible nights and are more forgiving of partial attendance. Weekend-only groups exist and are easy to find with the Saturday and Sunday filters. Guilds recruiting for a flexible raid size can fold you in without needing you on every night.
You can also flip the search: mark yourself as looking for a guild, set your days and hours, and let recruiters find you in the player directory. Recruiters filter it by availability for the same reason you do.
