MSport

MSport is an all-in-one utility app whose date calculator can answer the question "what day of the week was that?" for any date in history, no calendar flipping, no guessing, just an instant answer. The weekday lookup accepts any date you enter and immediately tells you whether it was a Monday, Tuesday, Wednesday, or any other day of the week, covering dates in the past or future with equal ease. This is useful for more situations than you might expect: verifying what day a historical event occurred, confirming the day of a birth certificate or contract date, planning recurring events, or just satisfying curiosity about any specific date. The date difference calculator adds a complementary function: enter two dates and MSport returns the number of days between them, useful for project planning, contract duration, and deadline management. MSport runs fully offline and needs no account, the weekday lookup, date difference, and eight other tools are available immediately with zero setup.
