excel - Check if date falls between some range -


i have data similar to:

a1: id b1: start date c1: end date

i have worksheet (call new) has

a1: id ,  b1: date

i need find out if date id in new worksheet in previous worksheet. if date start date, end date or in between, want show there record exist.

solution here assuming more practical:

  • a master sheet id, start date, end date (multiple rows)
  • other sheets id , date (multiple rows)
  • uses user defined function (udf) , id cell input
  • one drawback need "calculate sheet" if other sheets has been updated

sample screenshots:
formula sheet1 d2: =findduplicates(a2)

sheet1sheet2sheet3

code in module:

option explicit  function findduplicates(orngid range) string     dim sid string, dstart date, dend date, lcount long, swhere string     dim ows worksheet, orngfound range, dfound date, sfirstfound string      sid = orngid.text     dstart = orngid.offset(0, 1).value     dend = orngid.offset(0, 2).value     lcount = 0     swhere = ""     each ows in thisworkbook.worksheets         ' find ids in other worksheeets         if ows.name <> orngid.worksheet.name             sfirstfound = ""             set orngfound = ows.cells.find(what:=sid)             if not orngfound nothing                 sfirstfound = orngfound.address                 ' keep searching until first found address met                                     ' check dates, add if within dates                     dfound = orngfound.offset(0, 1).value                     if dstart <= dfound , dfound <= dend                         lcount = lcount + 1                         if lcount = 1                             swhere = swhere & lcount & ")  '" & ows.name & "'!" & orngfound.address                         else                             swhere = swhere & vbcrlf & lcount & ")  '" & ows.name & "'!" & orngfound.address                         end if                     end if                     set orngfound = ows.cells.find(what:=sid, after:=orngfound)                 loop until orngfound.address = sfirstfound             end if         end if     next     if lcount = 0 swhere = "not found"     findduplicates = replace(swhere, "$", "") ' removes $ sign in addresses end function
