When using the MIT license (or any license in general) in a project, should the license date next to my name reflect the initial creation year of the project or the current year, especially if the project is still actively being developed and maintained?
Have a look at this other question / answer.
In principle you should have the year of first creation as also specified in this official document.
But if during a following year, you or somebody else made some relevant changes, then the license date should be update listing also the new year. To avoid having a long list of years, also a range of years can be used.
