Describe the bug
A clear and concise description of what the bug is.

I am seeing an issue with isDate() validation chain that sems to point to a recent fix not being propagated to npm registry.

Examples
If applicable, add screenshots to help explain your problem.

npm registry and git master branch seem to be different.

I only checked isDate.js validator and the version on npm is missing a rectent fix. The code seems to be from prior branches.

Thanks,

Node.js version:

Yes, master does not reflect our latest release but we have planned a new release that contains this fix. See #2269
