TrumpTime is a date calculator app available on iPhone. It allows users to calculate the time elapsed since the start of the Trump Administration, as well as the remaining days and overall days in the term. The app offers various options such as selecting a milestone, entering a time period since Inauguration, or displaying a four-year or eight-year term ending on specific dates.

One of the main features of TrumpTime is its progress bar, which visually illustrates the elapsed time since Inauguration. Users can also enable the "Time to milestone" feature to see the days from a specific date until a milestone, such as the 2018 Midterm Election.

In addition to its Trump-related features, TrumpTime includes a general date calculator. Users can calculate the time between any two dates, find the date that is a given time period before or after a known date, and even enter formulas using arithmetic operators.

The app also offers the option to display a text description of the elapsed, remaining, and overall time in office, which can be copied and pasted into other apps. Users can also choose to enable the app's icon badge to display the elapsed or remaining days, with automatic updates at midnight.

TrumpTime Date Calculator provides a versatile and convenient tool for tracking and calculating time in relation to the Trump Administration, as well as general date calculations.
