Auto extract data from master list into other sheets based off of month

Hey guys,

Unfortunately I cannot attach a file because I would get fired for putting information on the internet. In short, I'm trying to auto sort data into spreadsheets based off of the month the project was started. We have a "Master" spreadsheet with all the projects, dates started, and other information which is irrelevant here. I would like the projects and all the data to get sorted into the correct spreadsheet via month. So we have the master sheet, a sheet for january, february, march, etc. For example, if project A was started in January, B in february, C in march; this data would get sorted into the correct monthly spreadsheet (the master sheet will be continuously added to daily). I thought I could figure this out with a vlookup but soon realized I had nothing on my monthly sheets as a lookup value. Any ideas at this point would be great!

so what do you have to do for the lookup value to be all of one specific month. for example, pull all the projects started in January

you know what, I'm sorry, just realized the project name is to the left of the dates which make a Vlookup difficult to use. I attached a quick spreadsheet
