You can use strtotime    date   strtotime  2010-01-01 -1 year      The strtotime function returns a unix timestamp  to get a formatted string you can use date   echo date  Y-m-d    date      echoes  2009-01-01

Although there are many acceptable answers in response to this question  I don t see any examples of the sub method using the  Datetime object  https   www php net manual en datetime sub php  So  for reference  you can also use a  DateInterval to modify a  Datetime object    date   new  DateTime  2009-01-01     date- gt sub new  DateInterval  P1Y      echo  date- gt format  Y-m-d      Which returns   2008-01-01   For more information about  DateInterval  refer to the documentation  https   www php net manual en class dateinterval php

You can use the following function to subtract 1 or any years from a date      function yearstodate  years              now   date  Y-m-d             now   explode  -    now            year    now 0            month      now 1            day     now 2            converted year    year -  years          echo  now    converted year  -   month  -   day           number to subtract    1   echo yearstodate  number to subtract     And looking at above examples you can also use the following   user age min    -   1   echo date  Y-m-d   strtotime  user age min  year
