OmniaChron: Day Counter

OmniaChron is a visual day counter for countdowns, count-ups, date ranges, and real-world progress.

Track days until important events, days since meaningful milestones, or progress across any date range. See every timeline as a clear percentage, with progress bars that update in real time.

Use OmniaChron for launches, school terms, work deadlines, sprints, vacations, anniversaries, seasons, retirement dates, personal milestones, and anything else worth measuring.

Why OmniaChron is different:
Most countdown apps stop at “days until.” OmniaChron also shows how much progress has actually happened and, when needed, how much usable working time is left.

Exclude weekends, holidays, breaks, and off-hours. Then compare calendar time with working time so the number on screen makes sense.

Free and paid:
