@nanov Any specific reason to drop the moment.js requirement? I can see cases where it would be useful to have in the various scripts to send instructions with start and end-dates. For example to pull the statements from previous business day would be a lot more straight forward if we would use something like: https://www.npmjs.com/package/moment-business-days

Well, I personally thing this is an unneeded dependency of the client by-itself one may choose to use whatever he likes on his side.

With that being said, the library could benefit from utils like the one you described, and they are pretty straight forward to write in plain ( modern ) javascript and would be a good addition. Let's open a separate issue and discuss the API plus implementation details so we can get this rolling.
