Some other options  just for reference  -10 days ago   Available in Rails 4 DateTime now days ago -10    Just list out all options I know    1  Time now   10 days  2  10 days from now  3  -10 days ago  4  DateTime now days ago -10   5  Date today   10   So now  what is the difference between them if we care about the timezone     1  4  With system timezone  2  3  With config timezone of your Rails app  5  Date only no time included in result

This definitely works and I use this wherever I need to add days to the current date  Date today   5

days  years  etc   are part of Active Support  So this won t work in irb  but it should work in rails console

Use   Time now   10 days   or even  10 days from now   Both definitely work  Are you sure you re in Rails and not just Ruby   If you definitely are in Rails  where are you trying to run this from  Note that Active Support has to be loaded
