You rarely need to type a full date. Business Central understands shorthand in every date field.
t today; w work date.+1w, +3d, +1m, -10d: relative to today (or to the date already in the field).cm current month end; -cm month start; cw, cq, cy likewise for week, quarter, year.cm+1m: end of next month (useful for due dates); cm+30d.5: the 5th of the current month; 0503: 5 March this year; mo, tu: next Monday, Tuesday.The same formulas are what Payment Terms (30D, CM+30D), Reminder Terms and the planning parameters use, so once you read them in setup you can type them in fields.
