You can do date arithmetics even if the date command doesn't support it - at least on the day level - quite easily using the TZ variable (i suppose in the following example that you are in the GMT timezone. You will have to introduce a corrective factor if not.):

Code:
# print - "yesterdays date: $(TZ=GMT+24; date)"
# print - "one week ago: $(TZ=GMT+$(( 24*7 )); date)"
