# sorting ascending vs descending

I don't understand the difference between ascending and descending? Surely ascending means the most active/recent/popular/A first, and descending means the least active/recent/popular/Z first?

But it seems it's the reverse in most API routes. (I think there are a few where it's different but I always find it hard to get my head around asc vs desc)

but: when using descending with date/activity sorted routes the most recent/active items are shown.

Dates increase as time advances, so `1293861600` (Jan. 1st 2011) is greater than `946706400` (Jan 1st. 2000). Thus, a descending ordering puts the most recent dates first.

Because sorting by dates is much more common than by name, ordering is descending by default.

• Surely ascending means, as you go up the list the value gets greater? It doesn't say this in /usage – Jonathan. Mar 21 '11 at 7:33
• @Jonathan - that is what ascending means, and that's why the most recent dates are returned first in when `order=desc`; since they are larger than dates in the past. – Kevin Montrose Mar 21 '11 at 15:49
• ok I've just never understood ascending and descending I find they are uselessly indiscriptive and kind of generic. I'll just have to take 15 minutes to learn them. – Jonathan. Mar 21 '11 at 15:57
• I know I'm late, but I'll point out for the alphabet: think of it in ASCII (Unicode) numbering. Z is highest in number, while A is lowest in number. So a descending alphabet starts at Z and ends at A. – Adam Dunn Mar 24 '14 at 19:02
• @Jonathan. I know this explanation sounds a bit 'Peter & Jane', but the way I visualise this, is: I am at the bottom of the stairs. The first stair is stair number 1 and the second stair is stair number 2 etc. As I "ascend", the stair number increases, so I am going from the lowest numbered to the highest numbered stair. And dates are actually just numbers [seconds actually from 1970]. So with date order=asc, means that you see the least recent [lowest number] dates first & date order=desc, means that you see the most recent [highest number] dates first! – Charles Robertson Oct 29 '17 at 16:56
