Date Calculator makes it effortless to work with dates and time — three focused tools in one fast, private app.
DAYS BETWEEN
Find the exact difference between any two dates, broken down into days, weeks, months, and years — plus hours, minutes, and seconds. Choose whether to include the end date in your count. Perfect for counting down to events, tracking project timelines, or calculating someone's age.
ADD OR SUBTRACT DATES
Start from any date and add or subtract days, weeks, months, or years. Instantly see the resulting date, the day of the week it lands on, and how far it is from today. Great for figuring out deadlines, due dates, and future milestones.
TIME CALCULATOR
Add and subtract multiple time entries to get a running total. Enter hours and minutes across up to 20 entries and see the sum in both HH:MM and decimal hours. Ideal for tracking work hours, logging billable time, or totaling durations.
DESIGNED FOR SPEED
• Results update instantly as you adjust your inputs
• Your entries are saved between sessions

Whether you're planning a project, counting the days until a trip, tracking work hours, or just need a quick date calculation — Date Calculator has you covered.
