About

Days calc

Calculate the difference between two dates or add days to a specific date. This tool helps you determine future dates, remaining days until an event, or days passed since a past date. It conveniently saves your last calculation for quick access.

Highlights
  • Add days to a date
  • Calculate difference between dates
  • Count days, weeks, or years-months-days
  • Find remaining days until a date
  • Track days passed since a date
  • Saves last calculated date

Read full description

This app operates using dates and days: - adds the number of days to specified date and finds the new date - finds the difference between two dates in number of days, weeks or years-months-days Choose the date, enter the number of days, and get the result! It also saves the last calculated date and updates it when launching. You will know: - which date it will be after a specific period of days - how many days remain until specific date - how many days have passed since specific date No in-app ads, no subscription necessary!
