Overview & Capabilities

Converting years to days enables sovereign debt traders, fixed-income portfolio managers, and treasury bond analysts to calculate precise daily coupon accruals and bond maturity dates. Government bonds and fixed-income securities calculate daily interest based on actual calendar days traversed (e.g. a 2-year US Treasury note equals 730.5 days, a 5-year Treasury note equals 1,826.25 days, and a benchmark 10-year Treasury bond equals 3,652.5 days). Multiplying years by 365.25 yields exact day counts.
