Answering to myself...
You can use the attached script:

yes? go def_monthaxis_noleap_days.jnl 2002 2005 2001 mytaxis
name       axis              # pts   start                end
MYTAXIS   TIME                48 i   16-JAN-2002 12:00    16-DEC-2005 12:00
T0 = 01-JAN-2001
CALENDAR = NOLEAP
  Axis span (to cell edges) = 1460

yes? show axis/t mytaxis
name       axis              # pts   start                end
MYTAXIS   TIME                48 i   16-JAN-2002 12:00    16-DEC-2005 12:00
T0 = 01-JAN-2001
CALENDAR = NOLEAP
  Axis span (to cell edges) = 1460

      L     T                   TBOX      TBOXLO                TSTEP (DAYS)
      1>  16-JAN-2002 12:00:00  31         01-JAN-2002 00:00:00    380.5
      2>  15-FEB-2002 00:00:00  28         01-FEB-2002 00:00:00    410
      3>  16-MAR-2002 12:00:00  31         01-MAR-2002 00:00:00    439.5
      4>  16-APR-2002 00:00:00  30         01-APR-2002 00:00:00    470
      5>  16-MAY-2002 12:00:00  31         01-MAY-2002 00:00:00    500.5
      6>  16-JUN-2002 00:00:00  30         01-JUN-2002 00:00:00    531
