Do you wonder how long the 45th President has been in office? How many more days until the end of his term? What if he wins re-election - how long will it be then? TrumpTime is a date calculator. It displays the time elapsed since the start of the Trump Administration: the number of days elapsed, the remaining days and the overall days in the term. Pick today or any date. Select a milestone, such as one year in office, day 500 or the next Presidential Election Day. Or, enter a time period since Inauguration - for example, 2 years, 8 months and 27 days - to see that date. The progress bar illustrates the elapsed time since Inauguration. You can display a four-year term ending January 20, 2021 or an eight-year term ending January 20, 2025. Want to know the time until a milestone? Turn on "Time to milestone", select today or any date, and select a milestone, such as the 2018 Midterm Election. The display shows the days from the date until the milestone. Other features: TrumpTime includes a general date calculator. Open the calculator and pick any two dates to display the time between them. Or, find the date that is a given time period before or after a known date; for example, find the date that is 17 weeks and 4 days after today. You can enter formulas as the time period using the four arithmetic operators +, -, × and ÷, and you can chain multiple operations together. For example, you can calculate the date that is 7 × 29 + 3 months after a known date. You can display a text description of the elapsed, remaining and overall time in office, and copy it to paste into other apps, like Mail. The app’s icon badge can display the elapsed or remaining days. When enabled, the badge will update automatically at midnight each day. The progress bar can display the elapsed time in green or red. You can select the calculation style, either a day count, which counts both the start and end dates, or elapsed days, which excludes the start date.
