anyone know the syreet cleaning day for 13th btw 6th and 7th

Can anyone help me out? Does anyone know offhand what day of the week and time they do street cleaning on 13th street between 6th and 7th Aves? Particuarly on the left/south side? I'm home sick from work and really don't want a ticket. It's not a block I generally park on so I don't know offhand (and leave for work at 8am anyway so I don't generally check). I'm very sick and can barely walk and if I can avoid walking down there just to check I would really appreciate it. Thanks!
