Which schedules have no official calendar?

• VA disability: VA doesn’t publish a payment calendar, so we apply the timing in VA’s award letter and federal law (38 U.S.C. 5120(e)).
• Military active duty 2027: DFAS hadn’t posted its 2027 table when we last checked, so 2027 dates use DFAS’s rule, which matches all 24 of its 2026 paydays.
• DFAS civilian and Interior Business Center paydays: neither office posts a table of pay dates, so we show pay periods only.
