resetFor a record of time without caloric intake, start the fasting timer after the last food or caloric drink, not when you sit down to dinner. Keep that definition consistent so that different days are comparable.
Dinner start and dinner finish are different
If dinner begins at 6:30 pm and ends at 7:10 pm, the interval begins at 7:10 pm under this definition. Starting at 6:30 pm would add 40 minutes that still included the meal.
A later snack or caloric drink changes the point from which you are counting. That is a recording detail, not a moral judgment about the food. For common drink questions, see what breaks a fast.
Start the record when convenient, then correct the time
You do not have to keep the phone beside your plate. If you remember at 8 pm that dinner ended at 7:10 pm, start the session and use Reset’s time editor to record the earlier start accurately.
Check the date when making a correction after midnight. A 12:15 am reminder about yesterday’s dinner requires the previous date, not a start time later today.
Do not invent missing precision
If you only remember that dinner ended between 7 and 7:30 pm, avoid presenting a guessed minute as a carefully measured fact. You can use a reasonable estimate for a personal record, while remembering the uncertainty when interpreting averages.
For future entries, a quick ordinary note of the meal’s end time may be enough. Reset does not need a food photo or detailed nutrition diary to record elapsed time.
Keep the target separate
The start records an event. The target records an intention. Choosing a 14-hour target does not mean adjusting the start until the result looks complete. If the interval ends after 12 hours, keep the actual end.
Our manual logging guide explains the fields for past sessions. The schedule calculator can preview a plan, but it does not know when you last ate. Any medical or procedural fasting instructions take precedence over a personal timing convention.
