A few options I can think of.
  1. Have them use the axes toolbar. It already contains tools for zooming in and out.
  2. Have them enter the dates somehow, then use those to set the XLim properties of your axes
  3. Add 2 sliders, one that sets the min XLim value, and on to set the max XLim value
You can find a list of the properties you can set for a UIAxes here.

If you are in R2018a+, you can use uidatepicker component for user to chose a date.
Then refresh XLim property of your axes in uidatepicker ValueChangedFcn callback.
Here some lines to begin with
% Figure handle
hFig = uifigure()
% Axe handle
hAx = uiaxes(hFig, )
% Create date picker
hDatePicker = uidatepicker(hFig, 'ValueChangedFcn', @yourCallback);
function yourCallback(src, evt)
hAx.XLim = ..
end

does something go next to hFIG in the Axe handle?

Any property that you want to change. Here see documentation uiaxes
hAxe = uiaxes(parent, 'Property', Value)
