Time to Time is a simple yet powerful time calculator for working with times and durations. It's perfect for freelancers, on-site technicians, businesses or anyone who wants to make working with times easier!

Use it to find the duration between two times, add hours and minutes to a time, subtract hours and minutes from a time or perform complex calculations with any combination of times and durations.


• Calculate the duration in days, hours and minutes from one time 'to' another time.
• Add and subtract with hours, minutes and times of day.
• Perform complex calculations using multiple times and durations in the same expression.
• 12 and 24 hour time modes including a mixed mode for using both time formats in the same expression.
• Smart 12 hour calculations allow the app to automatically detect whether times entered are 'am' or 'pm' e.g. 9 to 5 = 9am to 5pm.
• Times can be added in a wide variety of styles such as 9, 9am, 915, 0915, 9:00, 3pm, 15:00, 1500.
• A 'now' button for quickly entering the current time.
• Access help and settings right from within the app.


Calculate how many hours you worked today:
9 to 5 - 10 to 10:15 - 1h =

Find out how much sleep you'll get from now until 7:30am:
'now' to 7:30am =

Add up all of today's jobs:
9 to 10:13 + 10:45 to 11:30 + 2:30pm to 4:37pm =

Add an assortment of time durations together:
1:13h + 2h + 0:15h + 28h + 17:45h =

I love this app for work. It helps out a lot except for when I need to divide. Can you please put a divide button on so I can see what I get for the half. It really is for work purposes. Thank you in advance!!
