Date To Date Calculator

Date-to-Date Calculator

Date To Date Calculator computes the time difference between two dates or performs date arithmetic in multiple calendars (Gregorian BC/AD, Julian, Islamic, Hebrew, Buddhist, Hindu). For Gregorian BC, enter only the year (e.g., -1000 for 1000 BC). For others, use MM/DD/YYYY, YYYY-MM-DD, or calendar-specific formats (e.g., 01/01/1447 AH for Islamic). Useful for historical research, planning, or scheduling across cultures.
