IMLD 2009 events

The 2009 observance included the official close of IYL.


The UN General Assembly resolution setting 2008 as International Year of Languages (IYL) also "welcomed" UNESCO's decision in 1999 to establish observance of IMLD.

The IYL was officially launched on IMLD, 21 Feb. 2008, and ended on IMLD, 21 Feb. 2009 (see above).
