Choose your 100 days
Find out what dates you want to do for your 100 days using the date calculator here.
Simply add in your starting date then the value of 100 days and you’re all set! You can also do it the other way round if you wish and subtract 100 days from the date you wish to finish.
For example, if you’re starting on New Year’s Day (1 January) you’ll finish on 11 April. If you want to complete your challenge just in time for Easter, 100 days ahead of 18 April, and the Easter weekend, is 8 January 2019.
