Expert writing Tips
Best practice
In technical contexts like wireless sensor networks or clinical trials, ensure that the starting and ending points of the duration are clearly defined to avoid ambiguity.
Common error
Writers sometimes use 'til with an apostrophe, thinking it is the correct abbreviation of until. In fact, till is an older and perfectly legitimate word in its own right. Avoid using the single-L version 'til in formal prose; stick to until or the double-L till.

Ludwig's WRAP-UP
The phrase "duration till" is a functional temporal expression used to denote the span of time leading up to a specific conclusion. While it is widely present in scientific data reporting—found in sources like BioMed Research International and Computer Networks—Ludwig AI highlights that it is not the most standard choice. For a more polished and formal tone, writers should generally opt for "duration until". However, in technical contexts where brevity or specific data parameters are required, "duration till" remains an acceptable and frequently utilized tool for defining time intervals.
