The chart above (using info from fivethirtyeight.com) shows each president's job approval after he had been in office for 456 days. It is an average of the polls taken. For the first time of his administration, Trump is not the lowest rated. His 40.3% is 3/10 of a point higher than Carter's 40%.
That should not be any cause for celebration for Trump though. Carter's 40% showed his presidency was in trouble -- and Trump's 40.3% shows his administration remains in deep trouble.
