What Does DTE Mean? Days to Expiration, Explained
You'll see “DTE” everywhere in options trading. It's a simple count with big consequences — because how many days an option has left shapes how it behaves.

DTE stands for Days to Expiration — how many days until an option expires. A 30DTE option has a month left; a 0DTE option expires today. It's a simple count, but it drives one of the most important forces in options: time decay.
Why DTE matters
An option's extrinsic (time) value erodes as expiration approaches — theta decay — and that erosion accelerates as DTE shrinks. A far-dated option loses time value slowly; a near-dated one bleeds fast. So DTE tells you how much time your thesis has to play out and how quickly the clock is working against a long option.
Why 0DTE is a different animal
0DTE — zero days to expiration — is the extreme: the option expires today, so time decay is brutal and fast, and the position is pure short-term direction with no tomorrow. That makes 0DTE ideal for intraday scalping (cheap, responsive, no overnight risk) but unforgiving (theta punishes hesitation). It's the instrument NoVo is built around — see the 0DTE scalping guide.
DTE is the countdown clock on your option. The lower it goes, the faster time value melts — and at 0DTE, the clock runs out today.
The quick takeaway
DTE = days left until expiration; 0DTE = expires today. Fewer days means faster time decay and a more purely directional trade. Knowing the DTE is knowing how much time — and how much decay pressure — your option carries. Related: choosing an expiration for a day trade.
