The Barcelona Time Use Initiative for a Healthy Society (BTUI) already warms up for the celebration of the first edition of the International Time Use Week, which will take place in Catalonia from November the 23rd to 29th, as approved by the institutional steering committee composed by representatives of the Barcelona City Council , Generalitat de Catalunya and Diputació de Barcelona. The socio-sanitary crisis due to COVID19 has been the cause of the postponement of the Time Use Week to November. In addition, the International Time Use Week will be the embryo of the International Time Use Week 2021, which will also hold the 43rd IATUR conference in Barcelona.
