have to attend a meeting every day that lasts one hour

[tufguy]

We have nine hours to complete our work. However we have to attend a meeting every day that lasts one hour then we do have to check our yesterday's work as well for errors which takes about two hours so it leaves us with only six hours to work for the present day. So, ultimately we are short of three hours every day to complete our target.

Please check my sentences.

We have to check our work that is from one month ago.
