HowLong? - Date Calculator

How long until your next big day? How much time has passed since your first date? HowLong? brings day counting, anniversaries, age and everyday date calculations together. Calculate a result, save a meaningful date and turn it into a photo card to share. COUNT DOWN AND COUNT UP See the time since a birthday, first date or wedding. Count down to payday or Christmas, or create a custom date with your own title. Keep the moments you care about close at hand. MORE WAYS TO CALCULATE Find the interval between two dates, add days to a date or calculate age from a birthday. Calculate working time with start and end times and a break deduction. Compare times between cities when planning across time zones. YOUR SAVED DATES Save dates, search your list and mark favorites. Set annual anniversaries and enter solar or lunar dates. Reminder delivery depends on device permissions and settings. SHARE A PHOTO CARD Choose from 100 photographic designs inspired by nature, travel, love and celebrations. Create an image card with a saved date or calculation result and share it through compatible apps. MAKE IT FEEL LIKE YOU Choose the classic appearance, a blue theme or dark mode.
